How to make a hole in hardened steel without drilling. How to make a hole in a pipe with your own hands Making a homemade drill

If you need to make a hole in glass bottle, then you do not need to buy special equipment. This can be done at home with your own hands. You can drill with either a regular drill or a screwdriver.

It is preferable to use a screwdriver, since it has fewer revolutions (high speeds are not needed for drilling glass). It is recommended to use a drill with pobedit inserts, but if you don’t have one, you can take regular drill for metal work, for example, this instruction uses a drill with a diameter of 8.2 mm made of P6M5 steel. Don’t believe those who say that you only need to use pobedit drills and nothing will work with ordinary ones. Now we will make sure of this.

You can learn how to make a hole in a glass bottle by watching the video:

So, to drill a hole in a bottle you will need:
- The bottle itself, for example, from wine;
- Bottle stand to prevent the bottle from rolling around when drilling a hole;
- Paper tape;
- Regular drill or a screwdriver;
- Regular drill;
- Water for cooling;
- Drills
- And a syringe.


It is necessary to secure the bottle from rotation. To do this, a stand was made in advance from ordinary wooden blocks: two long and two short, fastening them together with nails. If it is not possible to make such a stand, then you can make a small depression in the ground if you are drilling outside, or place two bricks or something else on the sides. In general, it depends on your imagination.

First thing to do- this is to wrap paper tape (several layers) around the bottle approximately where you plan to make a hole. After this, put a mark on the tape with a felt-tip pen - the center of the future hole.


The most important thing when drilling a hole is not to press too hard on the drill, as the glass may crack and the bottle will be damaged.


Let's get started
We drill in stages, adding a few drops of water from a syringe to the hole in between. This is necessary so that both the drill and the glass bottle do not overheat.


So that there are no cracks with inside bottles, you need to monitor the pressure and not overpress the drill, especially at the end of the work.
When the drill has gone through, you need to carefully drill the hole, making light rotational movements. This will make the hole cut smoother.

About input nodes engineering systems many individual developers remember during the installation of water supply and sewerage. If the technological holes in the foundation were not made when concreting the tape, they can be made independently in several ways, using different tools.

In the arsenal home handyman Most often, household power tools are present. Therefore, in 75% of cases, you will need to rent a hammer drill or a diamond drilling machine. The price of the service is 800 - 1500 rubles/day; in one day you can make with your own hands all the holes for the communication input nodes and ventilation ducts in the base part of the foundation strip.

The maximum diameter of the technological opening is necessary only for the sewerage system; the remaining holes can be made smaller. When self-concreting MZLF, the location of the reinforcement is approximately known from the design documentation. This reduces the likelihood of contact between the equipment and the rods inside the belt.

Attention! It is necessary to take into account that each cut rod is an automatic reduction in strength when tensile forces occur due to swelling of the soil.

Hammer

You can make a technological opening in concrete for sewerage using a hammer drill. It is recommended to use different modes of this power tool for different equipment:

  • drilling – when using crown equipment;
  • impact drilling - if a standard drill is installed.

Slotting with peaks and blades is not recommended, as this leads to the opening of microcracks that weaken the structure. The edges of the technological opening are torn and chipped, and more effort is required to ensure the tightness of the communications entry unit. The crown allows you to obtain almost perfectly smooth hole walls to bring pipes with a diameter of 50 - 110 mm through reinforced concrete.

Crown

To solve various tasks industry produces crowns various types. Carbide modifications are intended exclusively for installation of socket boxes. Diamond tubular crowns allow passage through 30 – 50 cm strip foundation all the way through to make a hole in one go. Such equipment costs from 5 thousand, which is not economically profitable for a home craftsman.

Therefore, step drilling technology is used to drill a 50 mm hole:

  • deepening to the length of the carbide bit;
  • cutting out the inner concrete cylinder with a pick or chisel;
  • installation of an extension 30 – 50 cm;
  • repeating operations until a through opening is obtained.

The disadvantage of carbide equipment is mechanical damage to the teeth (chipping, breakage) upon contact with the reinforcement. Diamond spraying of tubular modifications cuts both concrete and reinforcing bars equally easily.

Important! The power of the hammer drill must correspond to the diameter of the bit (from 2 kW for 50 mm equipment) in order to avoid injuries caused by the rotation of the tool body when the working body gets jammed in the thickness of concrete.

Boer

You can drill a hole of any diameter with a standard carbide drill. To do this, you need to mark the opening:

  • circle of required diameter;
  • marks around the perimeter depending on the size of the drill.

After which several through holes are drilled around the perimeter, the inner piece of concrete is knocked out or chipped with a chisel or a hammer drill blade. The disadvantage of this method is the torn edge and the highest possible labor costs. However, the technology allows you to save your budget by at least half in comparison with a diamond tube, which is unlikely to be needed in the household.

Use a chisel to remove the remaining concrete.

Angle grinders, furrow makers and wall chasers are useless for making through holes of small diameter. "Grinder" with equipment for stone or diamond blade you can cut a large-format opening in concrete according to a stepwise pattern of penetration into the structural material. However, for communication input nodes this is not economically profitable - the hole will be much larger the right size, the integrity of the reinforcement frame will suffer, concreting and filling the voids with bricks or sealing in any other way will be required.

Diamond drilling

Punching a hole for the sewer is the easiest and fastest way special machine for diamond drilling. The design of the equipment is as follows:

  • drill + tripod + air or water cooling tubes (a compressor and a pump are used, respectively);
  • base plate (frame) + rod + support for fixing the electric drive (analogue of a drill) with gear, collar.

The first option is cheaper to rent, however, it requires a certain skill. Diamond drilling machines with a base plate are easier to operate; they have transport wheels and fixation mechanisms to the horizontal, inclined and vertical faces of the reinforced concrete structure. The water cooling pump is usually built in with the tank.

To do through hole through reinforced concrete, the base plate will need to be fixed to the surface. For this, two blind technological holes of 12 mm are required. There are modifications with a vacuum plate that do not require additional concrete drilling. The air is pumped out by a fitting; rubberized sides provide reliable fastening even on rough surfaces.

Drilling vents in the foundation with a diamond drill.

It is most convenient to drill through holes through reinforced concrete yourself using machines with spacer posts. U different manufacturers The design is slightly different, but there are 4 required elements:

  • a support with a gear to which the electric drive is attached;
  • gear rack on a beam with a folding movable clamp;
  • frame in the form of a support platform;
  • telescopic rod for positioning equipment in space relative to the drilling surface.

Rent professional equipment in this case, it is preferable, since it ensures the safety of the home handyman, who most often does not have the necessary qualifications and experience.

One of the fragile materials is glass, which must be handled very carefully. To carefully drill a hole in glass without causing a crack in it, you should follow the recommendations and carefully select the tools for the job.

Special crowns and drills

First of all, you need to purchase special devices. For this you will need:

  • A drill with a pointed end.
  • Drill bits.

Pointed drill bit mainly used in cases where you need to make a small hole. Lance-shaped ones can be regular or diamond-coated, which provides smoother drilling. But it is difficult to work with such a product, so it is preferable to use the second option.

For making holes large diameter apply diamond-coated drill bits. The use of abrasive spraying is allowed, but with such a product the drilling is of insufficient quality. Therefore, it is recommended to use diamond-coated products, because with such crowns there is less chance that the glass will crack.

Depending on the hole you need to make, you can use drills of different diameters.

Necessary tools and equipment

In addition to the drill, you will need the following equipment for work:

  • Drill.
  • Scotch.
  • Stencil (thick cardboard or a sheet of plywood will do).
  • Water.
  • Gloves.
  • Safety glasses.

Drill must have adjustable rotation speed. It can be replaced with a screwdriver, which is more gentle. You can use both manual and electric. The main thing is that there is minimal drill runout. It is recommended to use a drill with a speed between 250 and 1000 rpm.

Stencil necessary to accurately drill a hole. To do this, a hole of the required diameter is pre-drilled in it, and then it is applied to the glass.

Scotch additionally protects against small glass fragments. Water will be needed to cool the surface that will be drilled. For individual skin protection, you must have gloves, and also glasses, which will protect the skin and eyes from fragments.

Glass preparation

Before starting work, you need to decide on the surface on which the glass will be drilled. It is best to use a table that is stable on the floor. It is advisable to cover it with thick fabric or cardboard so as not to damage its surface during the work. This will also prevent the glass from cracking.

It is impossible to drill glass while it is suspended, so use a flat surface to which the material will fit tightly.

After this:

  • Glass is degreased with alcohol.
  • Wipe clean with a soft dry cloth.
  • Placed on the prepared surface.
  • Tape is glued to the intended mounting location.
  • A stencil with a drilled hole is attached.

Using a stencil you can make the required hole more accurately. It is necessary to ensure that the distance from the edge of the glass is at least 25 mm, otherwise the product may crack.

There is a second method without using a stencil. For this we take the usual plasticine and glued to the glass around the drill hole. Plasticine will act as sides. Water is poured inside to cool the glass.

Step by step instructions

After the markings are made, the main part of the work is done. To do this, prepare a drill, which is tightly inserted into the drill. It is necessary to check that it is well secured. Then the drill is turned on and brought to the marked drilling location at low speeds. The drill must be held strictly perpendicular to the glass.

When the depression is approximately 3 mm, you need to stop and drop a little water into it. Turpentine or kerosene is also used to remove heat from glass that is released during drilling.

Water is needed to cool the glass surface.

Then continue drilling at minimum speed. You should not press on the tool while working, because the glass is very fragile, and the drill may break if you do not follow these recommendations.

Drilling rules

To prevent glass from cracking during drilling, you must adhere to several rules:

  • Turn on the drill at minimum rotation speed.
  • Hold the tool at right angles to the glass.
  • Do not apply pressure to the drill.
  • Drill slowly in several passes.
  • After each use, moisten the recess with water.

It is necessary to drill in several passes not only to avoid overheating of the glass, but also overheating of the tool. The drill also gets hot, so it needs to be constantly moistened with water.

Once the hole is made, you can remove small roughness that has formed around it using a fine-grained sandpaper.

If you hold the drill easily, you can prevent cracks from forming. In addition, the drill should not be rocked from side to side. It must be held strictly at a right angle.

In the video you can see the method of drilling thick glass. To do this, a method is used in which a hole is made on both sides.

How to make a hole with a larger diameter than the drill size

If you need to make a hole with a diameter slightly larger than the diameter of the existing drill, than the size of the drill, you can use a glass cutter. To do this, a hole is drilled according to the diagram described above. After this:

  • A nail is inserted into the hole.
  • A small rope is attached to the nail.
  • The end of the rope is tied to the glass cutter.
  • A circle is made.

The nail must be selected precisely according to the diameter of the hole so that it does not dangle, but stands firmly. The length of the rope, which is attached at one end to the nail and the other to the glass cutter, must be calculated so that it is equal to the radius of the desired hole.

After drawing a circle with a glass cutter, you need to make gentle tapping movements. Due to this, the circle will come out of the hole. Then the rough edges at the cut site are processed with sandpaper.

What to do if you don’t have the required drill

Quite often, you don’t have a suitable drill at hand. Therefore, you can use their replacement:

  • Make a hardened drill.
  • Use copper wire.

Do it yourself hardened drill you can use a simple technology: take a regular drill, clamp it with pliers and hold the end of the product over gas burner. When the tip turns white, it should be immediately dipped in sealing wax. After a couple of minutes, the drill is taken out and cleaned of particles of sealing wax.

To correctly drill glass with a tempered drill, you can use the diagram described above. The only difference is the need to constantly wet the drill so that it does not overheat.

Copper wire used when there is no drill at hand. To do this, the wire is clamped into a drill. Then a special solution is prepared from sandpaper powder (it is better to use coarse-grained paper), camphor, and turpentine in a ratio of 0.5:1:2. When everything is ready, the mixture is poured onto the glass at the drilling site, and then a hole is made.

How to make a hole without drilling

If you don’t have the necessary drill and drill at hand, then there is another way to make a hole in the material. You can use the old way. You must have with you:

  • Sand.
  • Tin (or lead).
  • Any thin and long object (you can take a wooden stick with a pointed end).

Work begins with degreasing the glass, onto which a small pile of wet sand is poured. A small funnel is made in it with a sharp object. The recess is made to the surface of the glass. The center of the funnel should coincide with the diameter of the future hole. A mixture of tin or lead (called solder) is then melted and poured into the funnel.

To prepare solder, a metal vessel and a gas burner are used.

After a few minutes the sand is removed. You get frozen metal, at the end of which there will be frozen glass. It should come off easily from the surface. The result is a perfectly smooth through hole in the glass.

When drilling glass, the main thing is to adhere to the technology of work and select the right material. To make a high-quality hole in the material without damaging it, it is advisable to:

  • It is better to use a diamond-coated drill.
  • Carefully select the diameter of the drill.
  • Choose correctly work surface: It must be stable.
  • To prevent the glass from slipping, the table is covered with cloth, cardboard or plywood.
  • Do not drill tempered glass, which may burst into small fragments.
  • Do not put pressure on the drill while working.
  • Carry out all actions slowly, constantly wetting the hole with water. This will help avoid overheating of the material and prevent the formation of cracks.
  • Carry out the work wearing protective gloves and goggles to prevent splinters from getting into your skin and eyes.
  • Before starting work, it is better to practice making holes on an unnecessary piece of glass.

When drilling a hole, you don’t need to try to do all the work at once. This is a rather labor-intensive process and takes a lot of time.

It often seems that such a fragile material as glass can only be processed to an experienced master. But if a beginner treats the work with understanding and does it slowly, calmly, unhurriedly, then you can drill a hole in the glass perfectly.


So in a simple way you can do not only round hole in hardened steel, but also a hole of any other shape in without extra effort. Chemical method will help you out and make the task easier. The method does not require expensive chemicals; all ingredients can be found in any household.

Will need

I suggest a simple way to make holes in high speed steel. To work you will need:
  • any product made of high-speed steel;
  • marker;
  • nail polish;
  • nail polish remover (can be replaced with white spirit or acetone. I chose the remover only because of the pleasant smell, and it’s the same acetone);
  • cotton wool;
  • empty plastic container(bottle);
  • salt;
  • a homemade device made from a charger and two nails.

Making a hole in metal without a drill

Apply nail polish remover to the cotton wool and degrease the surface of our workpiece.


Apply varnish to the desired area. The varnish must be applied in a thick layer on both sides. Don't forget to coat the ends thoroughly. Leave the workpiece for 10-15 minutes to allow the varnish to dry.


On the dry surface, with a marker on both sides of the workpiece, I mark the place for the hole. I choose the location arbitrarily, now I need to show how you can make a hole using this method. For example, you need to install a regular factory rivet. The diameter of the hole should be slightly smaller than the size of the rivet.


Then use a knife to remove the varnish inside the hole outline. Do this on both sides.


Pour water into a container and add 3 tablespoons of salt. The height of the water in the container should be 10 mm less than the height of the varnished area of ​​the workpiece.


I take a device made from a hair clipper charger and two nails. The nails will serve as electrodes - I connected them to one contact. The other contact is simply bare, stripped wire. I use charger 12 V, but a regular mobile phone charger will cope with this task.


The stripped wire should be positive, the electrodes should be negative. We attach the positive wire to our workpiece using a clothespin. Then we lower the nails into the water.


You can make slits in the container to fix the position of the nails. Plugging the charger into a power outlet. After switching on, the water around the electrode nails begins to bubble, and the cleaned hole mark turns black.



Note: to check the polarity of the wires, you must connect the charger. If water starts to bubble around the nails, it means it's a minus and you connected correctly. The appearance of bubbles in the water around the workpiece indicates that the minus is connected to it and the wires need to be reconnected. The negative must always be connected to the electrodes, the positive to the workpiece being etched!
Leave the container for one hour, 30 minutes after the start of the process you need to change the water. I turn off the charger and take out the workpiece.


A through hole appeared in the intended location. In order to make the hole diameter larger, the process can be continued. Or file uneven edges with a file.
This is how, by etching high-speed steel using the most ordinary objects, you can make correct hole.

There are times when you need to make a hole in the glass. In reality, this is not so easy to do. In this article you will learn a couple of ways to solve this problem.

How to drill glass

If you need to make a hole in glass, for example, to hang a mirror or insert a handle in a glass cabinet door, you can use these simple methods.

For the first method you will need:

  • the glass itself
  • metal drill
  • drill
  • acetone
  • turpentine
  • alcohol

To drill a hole in glass you need to lay it on flat surface, for this you can use a large sheet of plywood; the edges of the glass should not hang down.

We set the rotation speed of the drill bit on the drill to “one” or “minimum”, depending on the configuration of the drill. It is necessary to avoid strong beating of the drill so that the glass does not crack during drilling; in this case, a drilling machine is better suited.

Use acetone or alcohol to degrease the surface of the glass in the place where we will drill it. The drill is placed in the center of the intended hole, the drill is turned on, while drilling you need to gradually drip turpentine onto the glass at the drilling site. You can simply make a small funnel circle out of plasticine and pour turpentine into it.

To prevent the glass from cracking, you need to press the drill lightly, without unnecessary effort.

In the second method you will need:

  • glass
  • solder in the form of lead or tin,
  • wet fine sand
  • a stick sharpened to a cone, and the tip of the stick should have the diameter of the intended hole
  • alcohol or acetone.

The work is done like this: the surface of the glass is degreased in the place where the intended hole will be located. Sand is poured onto the drilling site, in a heap about three centimeters in height. A hole is made in the sand with a stick so that a funnel is formed, the molten solder is poured into the funnel.
