How to drill a hole in glass at home. How to make a hole in hardened steel without drilling Special core bits and drills

From time to time, situations arise that require the creation of holes of different diameters in the glass. For example, this is required when installing mirrors or when installing various devices on glass. This is a very rare type of work, and therefore calling a specialist can be very expensive.

You can do it yourself necessary work and do without the services of a master. However, you need to understand that glass is a rather fragile and expensive material, so you should carefully prepare before you start drilling.

Composition and stages of production

Common glass contains silica sand, lime and soda. Various additives greatly affect the final properties of the material, but quartz sand remains the main component, and its amount reaches 75% in the mixture. The lime component adds shine, strength, and protects against the effects of many chemical substances... Soda can significantly lower the melting point of the mixture. The most common additional components include:

• Lead gives extra shine and ringing.
• Manganese, nickel and chromium are used for various shades.
• Boric acid gives strength, shine and reduces the coefficient of thermal expansion.

Industrial glass production includes the following stages:

Currently, there are many types of this material, depending on the components used in production. The most common are:

Drilling attachments and working rules

Most often, the need for drilling arises when using industrial glass, quartz, crystal. These types are often fragile, therefore unskilled attempts to make holes most often end in damage to the workpiece, so the process must be approached very responsibly.

Drills for metal and concrete are not similar in shape to special glass drills. They must be worked very carefully, and if possible, then not used at all. But if only these types of drills are available, then it is best to use carbide concrete or spear-shaped drills on the tile. Drills for metal must be hardened.

There are also special attachmentsdesigned specifically for glass:

• Solid carbide drills with feather or spear shapes in various diameters. It is highly advisable to use those that have diamond dust on the cutting part.
• Drill, presented in the form of a tube. This view glass drills can be used when a large diameter hole is required. When working with this attachment, it is advisable to use a drilling machine.

When carrying out drilling work, you must adhere to the following rules:

Surface cooling can be done in several ways:

• Cover the drilling site with plasticine and pour water.
• Place a damp cloth or cotton ball around the hole to be machined so that the water gradually flows into the depression.
• The drill itself can be wetted, and a break in work will allow the drilling tool to cool down.

Ways to make a hole in glass without a drill

In the absence of a drill and the possibility of purchasing it, you can make holes by other methods or make a homemade drill, but such methods do not have high accuracy and quality, as a result of which they can lead to damage to the glass surface. Still, some methods can theoretically be applied, so they should be listed.

With sand and solder

Pretty interesting waythat does not require drilling skills and tools. To use it you will need:

• Sand.
• Low-melting solder, such as tin-lead.
• The container in which this solder will be melted.

The surface in which you want to make a hole should be degreased and dried, after which a pile of wet sand is poured over the area in which the hole should be located. Further, it is necessary to make a depression in it of such a diameter, which is required by the hole being created.

Solder melted with a torch or soldering iron is poured into the formed hole, after which you need to wait for it to completely harden. With the subsequent removal of sand and hardened solder, a hole of the required diameter remains on the glass.

This method is distinguished by high quality and accuracy of the resulting hole.

Making a homemade drill

In the absence of special attachments for working with glass, you can make them yourself.

This will require a metal rod and a simple glass cutter with a diamond roller. To turn it into a drill, you need to cut a hole in the rod into which the roller is inserted and fixed so as to remain stationary relative to the rod.

The resulting workpiece is fixed in a drill chuck, and then drilling is performed according to the principle of a conventional drill.

You can also prepare a conventional drill, for example for metal for working with glass. To do this, you need to clamp it in a vice or pliers and keep it in the flame of a gas burner until the metal is white-hot. After that, the drill is dipped in warm water or oil. This hardened tool is suitable for drilling glass.

With a metal tube

A piece of metal tube is also suitable for making a hole in the absence of a drill. To do this, cuts are made on the part of the pipe that will be cut to create a cutting part in the form of teeth. When applying such works, auxiliary abrasive powders or pastes should be used, but this method is quite laborious and often leads to damage to the workpiece.

Using a glass cutter

An ordinary glass cutter can also replace a drill, the main thing is not to make sharp jerky movements, not to press on the glass, and to tap the formed cut surface with the handle of the tool.

To cut holes of large diameters with a glass cutter, you can use a compass, fixing one part of it in the center of the intended hole, and with the second part (on which the glass cutter is fixed) cut the surface.

It is often necessary to drill glass at home. Videos of these works can be found on the Internet, they cover such topics well in simple language with illustrative examples.

If possible, work is best done with a screwdriver, and not with a drill. This will give a softer drilling method and reduce the chance of damage to the glass surface. In addition, it is recommended to wear protective goggles and clothing, and to drill in a non-residential area

It is important to observe the minimum indents from the edge of the workpiece: for brittle materials - at least 25 mm, for common types glasses - not less than 15 mm.

It should be remembered that glass is a rather fragile and expensive material, so you need to work with it very carefully. In the absence of experience in such work, it is important to practice on unnecessary pieces of glass in order to gain experience and understanding of the process.

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

I used to suffer for a long time, drilled along the contour, then grinded these teeth, swore at the fact that I had polished off excess or screwed up parallelism. In general, for everything that concerns the machining of the material, I have my hands out of my ass. And there's nothing you can do about it. But where the hands cannot, the head must work. And they came up with a simple and effective solution.

So. It is necessary 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 bend the corners as clearly as possible. We do it on the outside, front, side! Then the corners are drilled through with a thin drill. It is important to take a thinner drill. The thinner the more accurate our hole will be.

We take a ruler and a sharp scalpel. You can use a clerical knife or whatever is at hand. The main requirement is that it must be very sharp, tough and not loose. I do things like this with a cutter.

Along a ruler from hole to hole, exactly according to the size of our hole (no more, no less, just like that!) We make cuts. The deeper the better, but it is possible without fanaticism. Because the deeper you cut, the greater the chance that the blade will break off and we will kill the outer surface, and this is not that - it is ugly. The holes here also rule by the fact that the scalpel tip 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 perfectly the first time or will have to be trimmed.

Everyone, got four pieces inside. Now you 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 on the edges will prevent the crack from going further than necessary.

It took me no more than 10 minutes to poke this hole. This is with garbage collection and the distraction of photographing and finding a scalpel or a drill.

Installation of any communications in the house, be it water supply, sewerage or gas pipes, involves their passage through walls or other ceilings. In this material, we will tell you in detail how to make a hole for a pipe in a wall, floor or other structural elements of a building, and what you need to pay attention to in the process of performing work.

First of all, we note that the method of how to drill a hole in the wall for the pipe will depend on specific conditions, for example, the type of partition, its external decoration, as well as the location of the pipeline.

How to make holes in the wall

Before drilling a wall for a pipe, it is worthwhile to figure out what standards must be observed in the process, especially if you are going to drill a load-bearing wall.

When cutting a hole for communications, make sure that such structural elements buildings like:

• protective and reinforcing gratings in the thickness of the wall;
• ventilation ducts, if any in the building;
• wiring lines.

At the same time, when equipping holes for pipes in the wall, make their diameter slightly larger than the cross-section of the pipeline so that you can mount a protective sleeve, and, possibly, insulate it mineral wool or other non-flammable material.

Technology for working with holes in the wall for pipes

Please note that before drilling brick wall under the pipe, it is important to make sure that there are no electrical wiring lines or reinforcing rods in the place of the intended hole. This can be done with a simple metal detector.

Preliminary work includes the following steps:

• markings are applied to the wall, indicating the exact place and diameter of the required hole, which coincides with the section of the pipe with the sleeve;
• a hole in the wall is cut out with a "crown" nozzle;
• in places where the nozzle cannot cope with very hard material, use a punch and hammer to destroy the wall;
• after passing a difficult section, the drill is completed until the desired hole is obtained.

It should be noted that steel drills are not suitable for working with concrete walls. In this case, you will need special victory drills that can cut a hole in materials, the thickness of which reaches 10-15 cm.

Performance of works of increased complexity

Special care should be taken when cutting utility holes when working with difficult materials such as tiles. Due to the sufficient fragility of this material, it cannot be drilled in the percussion mode.

If you need to make a hole large enough, you will need to know some tricks:

• to work with such materials, special diamond bits are needed, which are used for drilling at low speeds;
• for drilling a hole, you may need a device such as a ballerina;
• in order to avoid slipping of the diamond tip or ballerina with a smooth surface covered with hard glaze, it is advisable to first scrape off the glossy layer with a file at the place of work, or stick masking tape so as not to damage the rest of the tile.

However, there is an alternative way to work with tiled flooring. Although it is cheaper, the risk of damaging the material is much higher. In this case, several holes are made around the circumference of the tile using a 3-4 mm drill. The areas between the holes begin to be carefully broken with a well-sharpened chisel and hammer, thus forming a hole. To obtain the exact size of the hole, the edges of the tile are cut off with the same chisel.

How to prepare floor holes

The rules for preparing the marked holes are determined by the type of base laid and the type of decorative coating laid over it.

Immediately before starting work, you first need to find out whether it will be possible to remove a part by cutting or dismantling topcoat where pipes will be laid. If this list of works is not possible to carry out, that is, it is impossible to make a hole (for example, in a tile), then they are done using one of the methods described above.

Finally

Cutting a large section hole for a chimney is not so easy, but it is possible - it is enough to study the technology of work, and also take into account all the nuances that may arise in this case. You can more clearly understand the described process from the presented video material.

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

It is preferable to use a screwdriver, since it has less revolutions (you do not need high revolutions to drill glass). It is recommended to use a drill with victorious inserts, but if it is not there, then you can take a regular drill for metal work, for example, in this manual, a drill with a diameter of 8.2 mm made of P6M5 steel is used. Do not believe those who say that you need to use only winder drills and ordinary ones will not work. Now we will see this.

How to make a hole in a glass bottle, you can find out by watching the video:

So, to drill a hole in the bottle you will need:
- The bottle itself, for example, from wine;
- Bottle holder so that the bottle does not roll when drilling a hole;
- Paper tape;
- Conventional drill or screwdriver;
- Conventional drill;
- Water for cooling;
- Drill
- And a syringe.

It is necessary to secure the bottle from rotation. For this, a stand was made in advance from ordinary wooden bars: 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 drill outside, or put two bricks or something else on the sides. In general, it already depends on your imagination.

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

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

Getting started
We drill in stages, adding a few drops of water from a syringe to the hole at intervals. This is necessary so that both the drill and the glass bottle do not overheat.

To avoid cracks on the inside of the bottle, it is necessary to monitor the pressure and not to crush the drill, especially at the end of the work.
When the drill has gone through, you need to carefully ream the hole, making light rotational movements. This will make the cut of the hole more smooth.

When laying tiles, situations often arise when you need to make a hole in it: to bring the mixer pipes, remove the outlet or switch, hammer in the dowels for the shelf, install the toilet, and so on. This article will discuss how to drill tile for any required diameter.

Ways to drill tiles

• Special drills for tiles. Helps to make small diameter holes. The tile drill has no threads and has a pointed tip on the tip. There are tetrahedral nibs (nibs), but these are inferior as they will be difficult to sharpen if necessary. It can also be used when drilling in mosaic or glass.
• Drills with a victorious tip for concrete. It is found in almost every home, it is not necessary to buy a special drill. If the drill is not tipped, it can also be used, but the end will need to be re-sharpened like a conventional drill.
• Self-tapping screws with an LM tip (so-called fleas). Since the wall tiles are very soft, they can be drilled without a drill by screwing in self-tapping screws with a LM tip. On average, 2-3 screws are used for one hole.
• Tile crowns with diamond coating. They allow you to make holes of large and small diameters for sockets or pipes, installation of a toilet bowl. They have a fixed diameter and cost 300-1500 rubles, but they last for a long time. The minimum diameter that can be found is 5 mm. Perfect even for drilling porcelain stoneware.
• Circular drills (ballerinas on tiles). In addition to the sharp tip on the center drill, they have an additional movable cutter on the shaft. This is convenient because you can adjust the hole diameter and not buy multiple crowns for each size. Another plus is the price of 300-500 rubles. Ballerinas are well suited to drill a hole in the center of the tile, but if it goes over the edge, it will be extremely difficult to do this.

When using any method, you must turn off the impact mode of the drill / punch and set the minimum speed to avoid the appearance of chips.

Using a diamond core bit

Markup

Let's start with a typical case where you need to drill a hole in ceramic tiles under the output of pipes to the mixer in the bathroom.

Such things must also be taken into account, and try to make cutouts for pipes in the center of the tile. This is done by shifting the layout or changing the starting point of the laying to the desired location. If you can't install the tap exactly in the center, then you need to try to hide this fact as much as possible, and not highlight it by installing a number of decors or borders.

It is logical that both holes should be at the same height. Therefore, the first thing to do before drilling the tiles is to measure the same distance from the floor. In order not to overwhelm the vertical, we use a plumb line with a weight or a bubble / laser level.

Measuring and marking the wall

Next, you need to measure the required horizontal distance between the centers of the points and make two more marks. From the center of each point, measure the radius of the hole so you know where the cut line will go.

Drilling

Switch the drill to drilling mode and set the minimum speed. Insert a diamond-coated bit into the chuck. They are different, for example, for concrete, wood or metal - do not confuse them when buying. Also, make sure that there is as much diamond chips as possible on the working part. It is best to use a center drill to reduce the risk of misalignment.

We start drilling carefully, with a slight pressure on the drill, but so that it does not move from its place. When the glaze is cut through, you can increase the speed and pressure.


During drilling, it is necessary to provide water supply to the working part of the bit for cooling. Bosch has crowns that have a coolant inside (olive oil) that can be used dry.

If you are using a small diameter bit without a center drill, use it with a jig to avoid misalignment. You can do it yourself in 1 minute from trimming boards or plywood. Make a hole in it of the same diameter and use it as a conductor, pressing with your hand.

Fixing tiles

We apply the tiles and check the match with the pipes. If everything fits, we put glue on the wall, run it with a comb for even distribution with a thin layer and press the tile into place.

Ballerina use

You can make a hole with a ballerina in 5 steps.
