How to drill a cast iron pipe: methods | Heating water supply boiler room, heat, water
Before you learn how to properly handle a cast iron pipe, and in particular, how to drill a cast iron pipe, you need to understand what it is, where and what it is used for.
The main purpose of cast iron pipes is to drain waste water and for main collectors.
You may need the following tools:
Connection of cast iron pipes. SMU (both ends of the pipe are smooth); SME (one end of the pipe is smooth, the other has a detachable connection)
- electric drill or brace;
- drills with pobedite bits;
- grinder and metal wheels;
- marker for making marks.
There are two types of cast iron pipes:
- SMU (both ends of the pipe are smooth);
- and SME (one end of the pipe is smooth, the other has a detachable connection).
Before you start using pipes, you need to make sure that the location chosen for them does not contradict building codes. It is desirable that there are no turns or slopes.
Cast iron pipes are prohibited from being processed; only pipe cutting is permitted. Today, this metal is simply irreplaceable in some types of industry, which is why cutting and drilling cast iron is so important.

Methods for cutting cast iron pipes
In modern industrial conditions, there are many methods and various equipment that solve the issue of cutting cast iron.
In order to cut pipes, you can use a special device for cutting cast iron, a hacksaw for metal, or a grinder with metal discs.
In the process of cast iron production, when it is necessary to cut castings, techniques that use thermal cutting methods are widely used:
- arc;
- plasma;
- electrical contact;
- air-arc and others.
It is forbidden to cut a pipe with a gas torch, or to weld cast iron pipes.
When cutting with an arc method, electrodes of the following brands are used: ANR-2, LIM, OZR-1.

Drilling cast iron pipe
When drilling gray cast iron, as a rule, there is no need to use coolants and lubricants.
What does it mean to drill?
Drilling is the process of creating holes in solid metal using a cutting tool - a drill. And now about how to drill a cast iron pipe.
Many people face this problem and don’t know how to solve it. Gray cast iron can generally be drilled easily and does not require the use of coolant or lubricant.
But pipes are different, and in some cases more force is required. To do this, you should choose a metal drill with an angle of approximately 116-118 degrees, and when there are no special tools, you should drill with the smallest size drill, then use drills with a larger diameter, gradually increasing it.
- When the drill burns, you can lubricate it with water. In order to drill through cast iron, a hand drill is also suitable, the speed of which gradually increases. Directly when drilling, the speed should be small, as well as the pressure on the drill.
- In domestic conditions, it is recommended to use drills with pobedite bits; such drills should be used at low speeds, the force should be kept vertical and the cutting bit should be cooled frequently; overheating and blackening should not be allowed;
- In industrial conditions, if it is necessary to drill a cast iron pipe, machines with working tools that have working surfaces with appropriate sharpening are usually used.
Of course, they are equipped with a supply of coolants that ensure the desired operating temperature. In addition to the question of how to drill through cast iron, you need to think about the safety of this work. The array of processed material may contain voids and other defects.
This is often related to the amount of carbon in the cast iron and other components. These defects lead to the release of large amounts of dust and fine chips. In this regard, there are general safety rules:
- equipping the work area with a ventilated hood;
- use of a respirator or cotton-gauze bandage;
- use of safety glasses with closed sides;
- work in overalls, gloves and headgear.
It is also important to remember: before drilling a pipe, you need to make sure that there is no pressure in it and the liquid that it transports!

Tapping into a cast iron pipe
During the operation of a dacha or country house, sometimes it becomes necessary to make a tap from the water supply or an additional drain into the sewer for the washing machine.
This issue is resolved using the “inset” method. How to insert into a cast iron pipe?
In most cases, it is possible to use a ready-made tee, the diameter of which is slightly larger. You should cut off the part of the pipe where the pipe is missing.
The pipe usually has to be cut lengthwise, a hole drilled and a pipe welded to the remaining part.
The flange is attached to the pipe along the entire perimeter by welding. It is quite difficult to do this without special skills. In this case, you can use sealant and clamps, which will allow you to make an insert into almost any pipe in the house.

Drilling cast iron at home
Industrial development leads to the emergence of new materials with properties in demand for modern products and assemblies.
Despite this fact, cast iron, in all its diversity, remains an iron-carbon alloy, without which it is difficult to imagine any sector of everyday life, communications system or production equipment.
Fittings, shut-off valves, pipes, bathtubs, heating radiators, fastening elements for railway tracks and brake pads for cars, cast parts replacing steel ones. These are the components of a list that can be continued for a long time.
The processing of this material deserves special attention for large enterprises and home craftsmen. One of the main aspects is how to drill a hole in cast iron.
How to drill cast iron
Before starting work on drilling cast iron, pay attention to surface preparation. Removing burrs and cleaning the surface with sandpaper and degreasing it allows you to achieve a smooth hole in the right place without any unpleasant surprises. This preparation will allow the heat that is generated during mechanical processing of metal products to be removed.
The structure of cast iron, regardless of the form in which the graphite is in it, is prone to whitening when areas heated to critical temperatures are sharply cooled. At the same time, cast iron becomes brittle and prone to destruction at the slightest mechanical load.
Before you start work, you need to understand how to drill through cast iron - with what tool and what consumables are needed.
Drill selection
An ordinary metal drill is able to cope with the task. The only condition in this situation will be the correct degree of sharpening of the cutting tool.
Without theoretical justification, drill manufacturers, together with representatives of machining enterprises, found that the optimal sharpening angle range would be a run-up of 116-118 degrees.
The use of drills tipped from special steels and alloys is also justified if it is necessary to make holes in large quantities and large diameters. The most commonly used is will win. The design of the drill must correspond to the metal processing.
At enterprises, toolmakers got out of sticky situations by sharpening Pobedit drills for concrete with a diamond wheel. However, such manipulations require certain skills and may be unsafe when drilling. Selecting a drill for cast iron is an important step.

Tool selection
In factories and enterprises where the processing of cast iron workpieces is carried out on a wide stream, drilling machines are equipped with an emulsion supply to the point of contact of the drill. This technological move allows you to avoid phase transformations in the treated area.
A special requirement for drilling machines is the increased requirement for the ability to control and smoothly change the speed of rotation of the cutting tool and the feed into the workpiece. Specially developed substances are often used as emulsions. These are mainly sulfonated and chlorinated oils. For gray cast iron, kerosene can be used.
If there is no need to speed up the process, gray cast iron can be drilled without the use of a cooling lubricant.
At home, a drill with adjustable speed and quite powerful is used for drilling if it is necessary to drill a hole of significant diameter. If possible, be sure to use a device that locks the drill in relation to the workpiece. This will extend the life of the cutting tool. The main reason for its failure is misalignment, deviation from the vertical drilling axis.
Interesting information. After drilling the hole, treat its edges and cavity with sealant or epoxy glue. This way you can get additional protection against corrosion.
Subtleties of working with cast iron
Following simple rules will allow you to achieve the desired result, leaving the drills, tools, and hands intact:
- Control the load applied to the drill or machine without causing the drill to break. Cast iron products are mainly produced by casting. Shrinkage cavities and voids may appear. If a drill falls into such a void, it breaks in 95% of cases. There is a risk of injury or a broken drill bit in an unfinished hole.
- Do not allow the drill to overheat. Take a break from work. This will prevent the metal from softening and will extend its service life.
- To drill into a cast iron bathtub, use a pre-diamond tile and glass drill bit. This is a simple move to prevent cracking of the enamel.
- If the diameter exceeds 11mm, then the optimal solution would be to use a drill of a smaller diameter, and then the required size.
With the right approach and care, drilling into cast iron is not an impossible task. The information presented in this article gives a complete understanding of how to drill cast iron, all the nuances and subtleties.

What and how to drill cast iron
Before you learn how to properly handle a cast iron pipe, and in particular, how to drill a cast iron pipe, you need to understand what it is, where and what it is used for.
The main purpose of cast iron pipes is to drain waste water and for main collectors.
How to cut and install a tee into a cast iron sewer pipe?
When installing an additional sink or remodeling household premises, it becomes necessary to change the routing of the sewerage system. In some cases, it will be enough to organize 1 auxiliary tie-in or several. If the house has a fan system made of modern materials, then such work will not be difficult.
In many Soviet-built houses, the sewage system is made of cast iron pipes of different diameters. In this case, the work will require not only the ability to handle plumbing tools, but also knowledge of the basics of the plumbing craft.
Tapping into a cast iron pipe
Preparatory stage and necessary tools
Before making the insert, it is necessary to perform a number of preparatory work. In apartment buildings, sewer pipes run in technological shafts. To get to them, it is necessary to dismantle part of the wall masonry and prepare the place for work. The better this stage is completed, the easier it will be to work. To arrange the insert, you will need the following tools and materials:
- grinder with cutting wheel for metal;
- a set of metalwork tools;
- hammer drill or drill;
- fittings, tees, bends, adapters;
- sealing mastics, clamps.
Before starting work, it is necessary to prepare a drawing (diagram) of the area to be mounted indicating the exact dimensions. Any inaccuracies during installation may result in an increase in the volume of operations performed. In multi-storey buildings, it would be useful to notify neighbors about the work being carried out and ask them not to use the sewer during this period.
How to tap into a cast iron pipe?
Tapping into a sewer pipe can be done in several ways. It depends on the size of the pipes. Most often, products with an internal diameter of 100 mm and a wall thickness of 7.5 to 9 mm are used. To cut a pipe of a smaller diameter into a larger one, no special skills are required and such work will not be difficult, especially on a horizontal section.
If it is necessary to install a tee or connect products made of different materials, then installation may cause some difficulties. Before cutting into a cast iron sewer pipe, you need to accurately calculate the insertion location. It should not interfere with the movement of the main flow and lead to a narrowing of the flow area. On a horizontal section of the system, it is possible to install the pipe vertically or at an angle of 45°.
Due to the fact that plastic and cast iron pipes are manufactured according to different specifications, their outer diameters differ from each other. In order to join such products, rubber-metal couplings of the UR-12 type are most often used.
In this case, tightness is achieved using a rubber sealing ring, which is squeezed out when the structure is tightened. At the same time, this device ensures a tight connection with a deviation from the axis of 8°. The use of a coupling guarantees tightness at wastewater temperatures down to 0°C.
Installation of a transition from a cast iron sewer pipe to a plastic one. Master Class!
Tapping with a tee
Installation of such a device is possible both on a transit riser and in an existing outlet. In this case, the tee will be used as an additional element of the system's indoor wiring. The first option involves cutting out part of the riser and replacing it with the required unit. This operation can be performed using plastic or cast iron fittings. Most often, PVC products are used. This makes the assembly and installation of the tee much easier.
The installed unit is assembled separately in the room. In addition to the tee, experts recommend using a compensator. It will identify any inaccuracies in the marking of the insertion site and will facilitate installation. Before cutting out the required section of 110 mm pipe, it would be useful to secure the transit riser with fastening clamps to fix it immovably. Fasteners are installed below and above the cut part. In this case, you must not forget to make allowances for the installation and movement of the compensator (adapter).
Cut the pipe with a grinder. If it is not possible to make a circular cut, then it is completed using a hacksaw for metal. Experts do not recommend trying to do this with a hammer and chisel, because... The required part of the riser may collapse. The outer walls for planting are cleaned with a metal brush or scraper, and burrs are removed with a file. Before installing the fittings, the seats must be coated with sealant and the installation of the rubber O-rings must be checked.
The compensator is installed first and moves up for ease of installation of the tee. After its installation, the previously installed part is moved and secured in the socket. In order to remove unpleasant odors, the pipe is closed with a plug.
Installing a tee indoors is easier. The main difficulty lies in caulking the old input. For installation, shaped parts made of PVC are used. It is better to use bitumen-based mastics and pastes as a sealant.
Mortise using an overlay
This operation is performed without removing a segment of the riser. To do this, it is necessary to accurately determine the insertion point, drill or
cut a hole and install an adapter with a branch of the required size. Installation of the lining can be carried out on pipes of different diameters. The size of the hole to be made will depend on their size, which should not be more than half the diameter of the pipe.
The overlay can be purchased at the store or made by yourself. To do this, take a shaped part with a discharge of the necessary
size and cut it out, leaving part of the wall of the product. This is necessary to seal the installation site. To ensure sufficient density, the pipe is cleaned, burrs and casting defects are removed. The installation site of the lining is lubricated with sealant. The device is fixed using clamps. Excess paste is removed.
The industrial adapter is installed in exactly the same way, only it is secured with bolts. The tightness of the area is ensured by rubber sealing rings. Insertion using welding is not carried out on cast iron pipes, since it is impossible to achieve the required tightness.
Safety features when performing work
Installation work is closely related to the implementation of safety precautions. Following the rules will help avoid injury and equipment damage. Since a lot of unpleasant odors appear when working with sewerage, it is necessary to ensure the installation site has good ventilation. Working with power tools on wet equipment requires special attention and the use of protective equipment against electric shock.
To prevent the tool or dismantled parts from falling into the shaft, they must be secured and removed from the installation area after cutting. When working with electric cutting tools, be sure to wear a protective mask or goggles. Work should only be carried out with gloves. This will protect your hands from damage and infection.
Following the simplest rules will reduce the risk of injury and improve the quality of work.

The processing of this material deserves special attention for large enterprises and home craftsmen. One of the main aspects is how to drill a hole in cast iron.
Features of cast iron
Cast iron is an iron-carbon alloy, which is characterized by low cost and good performance characteristics.
- Gray cast iron.
- Ductile iron (with graphite spherical grain).
The material is resistant to compressive loads and has good resistance to corrosion processes.
Disadvantages include significant fragility, due to which it does not tolerate shock loads well. In high-strength grades of cast iron, this disadvantage is not so obvious, but at the same time they are much less amenable to processing. Therefore, cutting and drilling of cast iron is mainly used for gray grades.
How to drill cast iron
Drills with a mechanism for adjusting the speed of the chuck
For drilling at home, simple drills with a mechanism for adjusting the speed of the chuck are used. Such a tool for drilling cast iron must have sufficient power, especially if there is a need to drill a hole of significant diameter.
In industrial conditions, professional drilling equipment equipped with automatic control systems is used. Electronics allows you to control not only the rotation speed and feed rate of the cutting tool, but also the heating temperature of the drill and the volume of coolant supply. It is depending on the temperature conditions that the drilling parameters are adjusted.
Drilling at home will be carried out using a special device for cutting cast iron, which allows you to fix the drill motionless. This ensures the durability of the drill used, which usually breaks precisely due to tool distortions during the drilling process.

How to drill a hole in a cast iron pipe
Do you need to make a hole in a cast iron sewer pipe to connect a sewer outlet with a diameter of 40 mm?
Cast iron is different from cast iron and it is not always easy to drill through it. For drilling, select a metal drill with an angle of approximately 116-118 degrees. First, go along the intended contour with a thin (3-4mm) drill, and then expand the holes with thicker ones, constantly wetting them.
But sometimes you come across a carbon pipe, which requires you to spend a lot of time and nerves.
It’s easier to cut a piece of cast iron with a grinder and insert a tee
and as a result, get a high-quality and reliable connection.
Cast iron is different (there is high-strength cast iron, there is regular, gray), it is an alloy of iron and carbon.
It varies in strength and grain size.
In general, cast iron is drilled with metal drills.
I also drilled with Pobedit drills (with Pobedit brazing).
It is important to consider the following:
The most “global” disadvantage of cast iron is its fragility, we drill without impact, a drill is needed with a speed controller.
We do not press on the drill when drilling.
Do not overheat the drill, periodically stop drilling and cool the drill.
First, markings, and remember that you can only drill gray cast iron, high-strength cast iron simply has no options.
We drill with drills from smaller to larger diameter (in two passes).
This is basically all, practice and experience are important here, cast iron must be “felt” when drilling.
In general, your idea of inserting into a cast-iron pipe by drilling is not entirely correct, cast-iron sewer pipes are socketed, and if a branch is needed, then the pipe in the area of the socket is caulked, then, for example, a tee is followed and the connection is caulked back.
If the transition is from a larger diameter to a smaller one, then we insert such a transition into the tee, from one diameter to another, cast iron.
Cast iron is practically not drilled.
The best way to do this is, of course, in a turning workshop and using a special cutter and drilling machine, but I understand that not everyone has this opportunity, so we will think logically.
Cast iron is a fairly strong, but fragile metal; you can drill it with a regular metal drill and a drill, but you need a hole with a diameter of as much as 40 mm; you can’t clamp such a drill into a drill.
There is a way out: drill the outline of the hole with a thin drill and then refine it with a round file, this is troublesome and time-consuming.
Then this option, you need to find (buy) a diamond crown for the stone, but exactly, now tell me nonsense, it won’t work.
It will work! — I tried it more than once, even sawing steel with diamond wheels.
So you need a crown like this, of the appropriate diameter.
You need to drill at low or below medium speeds, constantly pouring water over the drilling area; if you overheat the bit, it will deteriorate.
Therefore, carefully, pouring water on the drilling site from a bottle, start working, you will see that cold cast iron can easily be drilled with a diamond core bit and you will get a neat hole of the required diameter.

How to drill cast iron at home. How to properly drill a hole in cast iron
Cast iron pipes can still be found in many houses and apartments; they are also widely used for laying various main lines. It is for this reason that sometimes it becomes necessary to cut or drill cast iron. Before drilling a cast iron pipe, you should familiarize yourself with some of the intricacies of this process.
Types of cast iron pipes and features of their installation
There are two types of cast iron pipes. The first type is SMU - pipes, both ends of which have a smooth surface. The second type is SME - pipes with a smooth surface on one side and a detachable connection on the other.
The installation location of cast iron pipes should not contradict building codes. If possible, there should be no slopes or turns in the pipeline.

How to drill cast iron with a drill - How to drill cast iron: tool, drill diameter
In connection with the development of the metallurgical industry, a variety of metals and their alloys appear on the market. Metal can replace steel since it is a material with a high price. When carrying out processing, you need to know how to drill cast iron in industrial production conditions and private workshops.
Drilling cast iron using a machine
What drills are used
When drilling, the following types of tools are used:
- drill for cast iron with a sharpening angle of no more than 118°;
- a tool with carbide inserts on the cutting edge, most often used to win;
- tool of a certain diameter.
Drill sharpening angle
Methods for drilling cast iron pipes
When installing sewerage or water supply systems, cast iron pipes are used. To create connections for transitions and inserts, you need to make holes. Processing is carried out in the following ways:
- industrial equipment;
- electric drills;
- using hand-operated devices.
How to drill a cast iron pipe
The processing speed can be affected by the technical characteristics of the metal. Some types of alloy can be drilled at high speeds and do not require the use of lubricants or coolants.
Different workpieces are subjected to different processing methods. For materials with high strength, metal drills with a sharpening angle of the cutting surface of 116° are used. If the master does not have a tool of the required diameter, you can use a set of different sizes. The work begins with a small drill, then the diameter of the tool is increased, thus achieving the desired result.
During processing, the drill heats up; to prevent tool defects, it is necessary to use water to reduce the temperature. The number of revolutions is gradually increased; it is forbidden to apply increased force to the device.
In a private workshop, drills with overlays made of pobedite are used. In this case, it is recommended to maintain a vertical position and low spindle speeds. During processing, the temperature of the workpiece and drill is monitored. Changes in color of the material as a result of sudden temperature changes are not allowed.
For industrial processing, machines with high rated power and high rotation speeds are used. During the drilling process, lubricating and cooling fluids are supplied to the workpiece and tool. At the same time, the normal temperature of the processing zone is maintained.
Carrying out work
When performing drilling processing, the following recommendations must be observed:
- Constant control over the force on the tool. As the load increases, defects in the form of cracks and cavities may appear on the metal. If the drill breaks, the technician may be injured.
- Overheating is not allowed during processing. Increasing the temperature of the workpiece will change the structure of the metal, causing it to become brittle.
- Before drilling, the surface of the part is prepared and the drilling site is cored.
- If the hole diameter exceeds 10 mm, then a tool kit must be used. They start with a small diameter and gradually achieve the desired one.
As a result of following the technology of machining cast iron parts, a master can achieve high precision holes.

How to drill a cast iron pipe yourself
To avoid problems when drilling a cast iron pipe, you need to know the properties of the material and the rules for handling it.
Cast iron pipes are used in pipelines designed to drain waste liquids and create main collectors. Among the advantages of cast iron are fire resistance and low noise levels. However, this metal requires more careful handling than PVC pipes. We also note that cast iron pipes, as a rule, are coated with an anti-corrosion compound inside and outside.
What tools do you need to prepare?
To work with cast iron pipes, you need to prepare the following tools:
- brace/electric drill;
- drills and bits from Pobedit;
- a marker that will be used to mark the pipes.
What methods are used for cutting cast iron pipes
Cast iron can be cut using a variety of equipment and using many methods. So, there are special devices that cut cast iron parts. You can also use a hacksaw and a grinder to cut metal.
During the production of cast iron, it is cut, if necessary, using thermal cutting methods. These can be plasma, arc, electric contact, air-arc and other methods.
Under no circumstances should pipes be cut using a gas torch. In addition, cast iron pipes cannot be welded.
To cut a cast iron pipe using the arc method, experts recommend using electrodes of such brands as OZR-1, LIM, ANR-2.
Features of creating holes in pipes
Drilling is the creation of holes of different diameters. For this, a cutting tool such as a drill is used. The process of drilling cast iron pipes is influenced by the characteristics of the metal. For example, gray cast iron is fairly easy to drill. This material does not require the use of liquid to lubricate and cool the metal during work.
However, there are different types of pipes, so in some cases you have to put in a lot more effort. In such situations, a drill that has an angle of 116 to 118 degrees is suitable as the main tool.
If you don’t have the necessary tools at hand, you can use drills of different sizes.
First you need to take a drill of the smallest size, after that you can use a slightly larger drill and continue to increase the size of the drill until a hole of the required diameter is drilled.
Temperatures may rise during drilling. To prevent the drill from burning, it must be cooled with water. A hand drill is quite suitable for drilling cast iron pipes. While performing work, you need to gradually increase the speed. But while drilling it is necessary to make small revolutions. In this case, the pressure on the drill should also be insignificant.
If cutting cast iron pipes is carried out at home, then you will need to use a drill with Pobedit attachments. This type of tool can only be used at low speeds, maintaining a vertical position. In this case, the metal should not be allowed to overheat. The cutting attachment must be cooled as often as possible, since the cast iron must not be allowed to turn black.
If cutting is carried out at an industrial enterprise, then a special machine is used to drill the pipe. As a rule, such machines have a working surface with special sharpening.
These tools are much easier to use because they have a water supply that cools the surface. This allows you to effortlessly maintain the temperature required for work without negative consequences.
A few notes about work safety
In addition to the question of what can be used to drill cast iron pipes, you should not forget about ensuring safety when performing this type of work on your own. This is especially important, since cast iron may contain voids and many other defects.
Most often, existing defects are caused by carbon and other components. Any defect in a cast iron pipe leads to the appearance of a significant amount of dust during drilling. Therefore, you should follow the safety rules:
- the place where the work is carried out must be equipped with an exhaust hood;
- when carrying out work, you need to use a respirator or at least make a bandage of cotton wool and gauze;
- It is imperative to protect your eyes by using safety glasses that have closed edges on the sides;
- the work must be performed wearing special clothing, and also protect your head and hands;
- When starting work, you need to be completely sure that there is no liquid left in the pipe and there is no pressure.
How to tap into a cast iron pipe
Often in a country house or dacha it is necessary to create another drain into the sewer system or drain it from the water supply network. In this case, you need to make an insert.
To carry out the work yourself, you can use a ready-made tee. Its diameter must be greater than the diameter of the pipe. You also need to remove the part from the tee where there is no pipe. As a rule, the pipe needs to be cut lengthwise, then a hole must be drilled and welded, connecting it to part of the pipe.
By welding, the flange is attached to the pipe along the entire perimeter. Without welding skills, it is difficult to complete such work. But you can use sealant and clamps that allow you to insert into any of the pipelines available in the house.
