How to make a hole in... How to drill a hole in glass. Video: methods of drilling pipes

Before you make a hole in a pipe, you should familiarize yourself with the appropriate techniques that allow you to solve this problem without the use of special equipment. In this article we will tell you about existing methods to help make holes in pipes made of various materials. You will learn how to give the hole the desired shape, as well as subsequently bore it.

Hole drilling tool

In order to complete the work, you will need to prepare the following tool:

• drill (electric or manual type);
• clamping vice;
• special marking tool;
• core, hammer and “round” file.

To work with metal pipe blanks, in addition to the items listed above, you will need high-carbon steel drills, as well as coolant. In addition, drills equipped with carbide tips can be used.

Let us immediately note that the drilling procedure without the use of special equipment is quite simple. All that is required of you is complete concentration and mandatory compliance with the relevant safety requirements.

Work of this type is carried out, as a rule, in a garage or in a special utility room(in a home workshop, for example). To avoid injury while drilling holes, you will need to use safety glasses and thick gloves. In addition, be sure to ensure that the drill bits are sharp enough and securely fastened in the drill chuck.

You can drill both metal and wood with the same drill, you just need to sharpen it at a different angle.

Work order

Before drilling a hole in a pipe, the following operations should be performed:

• secure the pipe section in a vice;
• apply appropriate markings to the drilling site;
• then in the center of the future hole, using a core, you should knock out a small depression (as they say, “punch” the drilling point). This operation is necessary so that the drill does not move to the side during operation and is fixed in the center of the marking;
• Once all these operations are completed, you can proceed to carefully and leisurely drilling the hole, starting with small-diameter drills and gradually changing them to thicker ones.

During operation, the drill must be kept strictly vertical, otherwise the drill may simply break under the influence of lateral loads. To accurately adjust the diameter of the hole, you can use a round file.

In order to make a square hole in a pipe, a regular round hole is first made, which can then be given a square shape using a file. Note that this method is quite labor-intensive and will require you to be very careful when working with metal.

When carrying out a similar operation with plastic or composite pipes, the easiest way is to use a rectangular steel rod. As such a rod is driven into a round hole, the latter acquires a square shape, after which it can be removed from the pipe blank. The irregularities formed during punching are subsequently removed using a regular file.

In plastic pipes, large diameter holes can be cut with a crown.

And in conclusion, we draw your attention to one more point characteristic of the type of operations we are considering. Since the drill becomes very hot when preparing a hole in the metal, coolant (water or waste oil) should be periodically added to the drilling site.

An interesting way of drilling through holes in small diameter pipes is shown in the video:

If you need to constantly make holes in pipes, you can make a jig for drilling holes:

I think each of you made a case for your electronic craft. And when making a body, one nasty problem often arises - making a hole with a shape other than a circle. For example, square, under an LED indicator.

I used to suffer for a long time, drilling along the contour, then grinding these teeth, cursing about the fact that I sanded off too much or messed up the parallelism. In general, I have my hands full on everything related to the machining of materials. And there is nothing to be done about it. But where the hands cannot, the head must work. And we came up with a simple and effective solution.

So. You need to make a square hole in the plastic case.

First, let's mark the hole. It is better to do this using a paper template - you need to mark the corners as clearly as possible. We do this on the outside, front side! Then the corners are drilled through with a thin drill. Here it is important to take a thinner drill. The thinner the hole, the more accurate our hole will be.

Take a ruler and a sharp scalpel. You can use a utility knife or whatever you have on hand. The main requirement is that it must be very sharp, rigid and not loose. I do things like this with a cutter.

Using a ruler from hole to hole, exactly according to the size of our hole (no more, no less, exactly the same!) we make cuts. The deeper the better, but without fanaticism. Because The deeper you cut, the greater the chance that the blade will break off and we will scratch the outer surface, but this is no longer the same - it’s ugly. The holes here also rule because the tip of the scalpel falls into them and the edge of the cut does not go further than the hole. Markup here the most important stage. It depends on him whether everything will turn out perfect the first time or whether it will have to be trimmed.

That's it, we got four pieces inside. Now we need to pick them up from the center and break inside!

The cut we made will give us a weak point at which the plastic will burst and break. And the holes at the edges will prevent the crack from going further than it should.

It took me no more than 10 minutes to pick this hole. This includes cleaning up trash and being distracted by taking photographs and searching for either a scalpel or a drill.

In this simple way, you can make not only a 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

• 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

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 a 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.

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.

Used for making large diameter holes 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 personal protection skin is a 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 thick fabric or cardboard so as not to damage its surface during work. This will also prevent the glass from cracking.

It is impossible to drill glass while it is suspended, so a flat surface is used 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 any small roughness that has formed around it using fine-grit 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 or drill at hand, then there is another way to make a hole in the material. You can use the old method. 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 the right 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.
