Artificial stone in appearance is sometimes difficult to distinguish from natural. And in terms of strength and resistance to external atmospheric influences, in some cases it can even surpass it.

Types of decorative stone: agglomerate, porcelain stoneware, artificial concrete stone.

It is very important that the weight of such a stone and its cost is much lower than that of a natural one.

These qualities largely determine its popularity in the external and internal decoration of houses and apartments. It is also used when laying garden paths, equipping bathrooms, making countertops and window sills. Therefore, many do-it-yourselfers are interested in how to cut such a stone, if you need to change its size or shape, how and how to drill holes, for example, for water pipes.

Artificial stone, made using different technologies, has different hardness. It depends on what components were used as filler and binder. All such varieties of stone can be divided into:

• agglomerate;
• acrylic stone;
• porcelain stoneware;
• artificial stone on a concrete basis.

Agglomerates, which include large quartz, granite, marble or limestone chips, and sometimes whole pieces of stone, bound with polyester resins, can be stronger than natural samples. The composition of acrylic stone includes fine-grained filler (up to 70%) and acrylic resin. This distinguishes it from agglomerates, makes it plastic when heated. It can be scratched or burned.

Porcelain stoneware products are superior in hardness to ceramics and glass, since their main component is highly compressed kaolin clay.

Stones made on the basis of sand and cement or Portland cement are similar in their properties to ordinary concrete. In some cases, manufacturers replace white cement with gypsum. Such artificial stones are less hard, easy to process, cheaper, but relatively easy to break down under the influence of moisture and low temperatures.

How and with what can a hole be made

To process a material such as artificial stone, you can use the same tools as when working with concrete products. A tool used for drilling the hardest materials can be successfully used for drilling all its varieties. This is usually done by one of the following items:

• perforator;
• drill;
• screwdriver;
• Bulgarian.

The grinder is used for drilling with the help of special diamond crowns, the design of which allows them to be used by winding them onto a shaft to mount the disk. The crown is installed at a right angle to the angle grinder body.

Drills or crowns are selected according to the size of the required hole and the hardness of the material used. As a rule, they have a tungsten carbide tip with Pobedit brazed, diamond tipped or diamond segment brazed.

Clamps are used to fasten the material. Apply dry and drilling with water to cool the cutting edge of the tool and the stone itself. In addition, water cleans the drill from cuttings, the edge of the drilled hole remains more even. There is much less dust during wet drilling.

In order to drill with water at home, a plasticine bath is made around the drilling site or a rubber ring is placed where water is added. When using a template, water can be poured directly into it by sealing the cracks with ordinary tape. Sometimes water is simply added little by little from a plastic bottle.

Artificial stone can sometimes have a polished surface on which marking lines are hard to see. In this case, paper construction tape glued to its surface will help. The lines are clearly visible on it, even if you draw them with a pencil.

How to win porcelain stoneware

For drilling porcelain stoneware, as it is very hard, use a drill with a special nozzle.

Drilling porcelain stoneware is not easy, it is one of the heaviest materials to process. To get even edges of the hole, you always need to start from the front side. At the exit, the drill can chip, and in this case it will remain invisible. If the slab you are about to drill is not already fixed to the floor or wall, place a flat board or piece of fiberboard under it.

If the diameter of the intended hole is larger than 6-8 mm, you must first drill it with a tool with a smaller diameter. To work with porcelain stoneware, it is better to use a puncher or a fairly powerful drill.

The drilling speed is low or medium, it depends on the diameter of the drill. The larger the diameter, the slower the speed. It is better not to use a drummer, there is a risk of splitting the plate. In some cases, especially with a large thickness of the material, a striker at low speeds is used if there are no voids under the plate, but everyone does this at their own peril and risk. When drilling, water must be used for cooling.

The best results are achieved when using a diamond tool. In practice, different drills are used: carbide tips on tiles, a diamond-tipped pen, diamond-coated tubes, diamond crowns.

Good results are obtained with Chinese-made thin-walled monolithic diamond-metal tubes, and they are inexpensive, about a dollar 1 pc.

The drill wears out less if you drill perpendicular to the plane of the material. To do this, a drill or hammer can be mounted on a vertical stand. The resource of the drill in this case is almost doubled.

It can be very difficult to start drilling with a crown on a smooth surface, it always tries to move to the side, scratching the surface. Therefore, to obtain a high-quality result, you can pre-make a template for holes of different diameters. The template is firmly clamped with clamps and prevents the bit from moving from the drilling point. You can also add water here for cooling.

You can start drilling at an angle to the plane if the template is not used: then the bit cuts into the stone with one side, and then aligns. But this method is best used on softer materials.

Similarly, you can drill holes in stone from concrete and agglomerates.

stone is a material that is very difficult to process. It is hard and fragile at the same time, which requires a special approach to it. Therefore, if you plan to work with this stone, it is important to choose the right drill by and also know abouthow to drill granitecorrectly so as not to spoil or split it during the process.

Basic rules for drilling granite stone

It should be borne in mind that drilling holes in granitealways carried out only at a low tool speed - usually, this is the first or second speed, but no more.

At the same time, the use drills should be with a change in speed, which directly depends on the diameter:

• if you are using a drill 6 mm in diameter, the number of revolutions per minute will be 2000 ;
• If drill for granitehas a diameter 12 mm, then the speed mode is set to 950 revolutions;
• if the diameter is 20 mm, the speed should be 700 revolutions.

So, the larger the diameter of the tubular drill (crown) on granite, the lower the speed of revolutions per minute.

It is necessary to carry out with the obligatory use of water to cool the cutting parts of the drill. Water also flushes out unwanted sludge.. She chills herself plates, helping to ensure the clarity and accuracy of holes. In professional industries, the water supply during such work is carried out under automatic pressure so that the granite drill is constantly washed and cooled. The use of water will not only help to carry out all the work as accurately as possible, but will also extend the life of any drill.

In case you are a beginner and for the first time come across how to drill a holeit would be best to pre-train by taking some unnecessary or defective granite small slab.

Do not mark with a simple pencil directly on the material: since you will be dealing with a polished slab, it simply will not leave any mark on it. You can make pencil marks on porcelain stoneware, but not on naturally occurring granite slabs. Better first n glue a strip of masking tape and already mark the place of drilling on it.

There are two methods of how to drill granite:

1. Position the drill at a slight angle and drill a trial groove first. Then, with smooth movements, align the crown to a position perpendicular to the slab. If you do not adhere to this subtlety, the drill will hang out on the polished stone without going deep.
2. The second method is also associated with this feature of the stone. If the centering of the drill is not accurate, and a certain skill has not yet been acquired by a novice master, it is very easy to scratch the polished surface of granite. It is best to use trimming first and try to drill a test hole in granite.If it works out well, use it as a pattern or template for later ones. To work "on a template", attach it to the section of granite that you plan to drill "clean" and fix it. The drill will definitely not crawl on the polish, and water can be fed into this hole.

What will you need

To the question about how to drill granitemany people say that this will require some kind of complex specialized tool, but this is not the case. An ordinary electric drill is suitable for work, it is only important that it has the option of regulating the speed of revolutions per minute.

In addition to the drill, you will also need:

• a diamond-coated drill having the desired diameter;
• ordinary water.

First of all, you need to fix the granite slab as carefully as possible, making sure that the surface on which it is installed is as flat as possible. Before starting work, you should mark the center of the future hole with a drill: this will help prevent the tool from sliding along the polish. Install a drill bit coated with a diamond coating (remember that using a drill bit without coating will not allow you to make a hole).

Drilling should only be done at low tool speeds without using the punching option. When you turn on the perforation mode, the granite may crack. Regularly ensure that the stone and drill are washed with water: as already mentioned, this contributes to cooling, cleaning, and the accuracy of the hole itself. In order to add water, you can invite an assistant. Or fill a plastic bottle with water, make a hole in the lid and use this “sprayer” to pour the drill and the hole on your own.

What to do if the diamond crown is missing

If there is no diamond crown and you don't know how to drill granitein this situation, you can carefully stick a plasticine ring 3-5 mm high around the entire circumference of the future hole. Place a little corundum, powder or diamond dust inside the ring, pour water. Fasten a copper tube to the drill (you can use a tube from any other non-ferrous metal). Now you can drill granite - also at low tool speeds, without using a hammer drill. You will certainly need water here too: first of all, in order to regularly cool the metal tube.

If there is no crown or tube - what to do?

In this case, the craftsmen suggest using an emergency and risky drilling method - using a drill from a Pobedit, at high speed with a constant supply of water.During this process, you will need to constantly sharpen the drill, because it will stop from time to time. Grind the drill with a semicircular needle file, very carefully, without overheating its teeth. Otherwise, the drill will soften and dull even faster.

Useful advice: if you are using a drill bit, it should be sharpened at least every 20-40 seconds of work.

Drilling on granite is a very difficult and painstaking job. It requires certain knowledge and skills. But if you wish, you can always purchase them by contacting more experienced craftsmen for advice. In order to practice, use stone fragments first: this will help both to “fill your hand” and prevent damage to a high-quality new workpiece.

Sometimes there are situations when working with stones when it is necessary to make a hole. Of course, when you have the necessary equipment at hand, it is much easier to do this and does not cause any inconvenience at all. Unfortunately, such equipment may not be at hand at the right time, but this hole is so necessary. For this case, you can use the tips provided and do it yourself.

Tool selection

First you need to choose special equipment in order to make a hole in the stone. In this case, a diamond drill is best. It is important to remember that a classic drill that has a winning tip is not suitable for such purposes, but they are sold at every turn in the construction market. In this case, the quality of drilling will be at the lowest level. In addition, such equipment can even spoil the work, and the necessary hole will not be made. Using such a tool, it quickly burns out and breaks the edge, and this is not a workable result and a good option.

diamond drill

Today, diamond drill bits are provided on the world market that are able to cope with such a task without any problems. Such a tool also has another name - a diamond crown. Using such equipment, it is possible to make a hole in the stone of any diameter that the master needs.

Why is the drill called diamond? This is due to the fact that the tip has a diamond coating. It is because of him that the work is greatly facilitated, while making the hole clean and even. As for the cost, it will depend on the thickness of the coating, as well as the life of the drill.

Any diamond hole saw can be used to make multiple holes, although there are exceptions. For frequent use of the tool, it is best to purchase a drill that has been made through thermal sintering. This method implies a rigid bond between the body of the drill and the granules. Such a tool is a much higher resource when compared with crowns, the manufacturing technique of which is diamond spraying.

The tool also differs in the way the crown is attached to the tool. Mounting is carried out both on the grinder and on the drill, unless of course there is a tail with an external thread and an internal M14. Fastening is carried out on a special installation producing diamond drilling.

After the tool has been selected, you need to start drilling a hole in the stone. But in order for the hole to be neat and even, it is necessary to use well-developed techniques.

Hole drilling technique

In order to drill a hole in the stone, you need to use water. This action is necessary because the water cools the cutting edge, thereby preventing it from overheating. Thus, the diamond drill will work much longer, and all the slimes will be washed out of the spores. In this case, the edge will not jam, and the stone will not overheat during drilling, which is guaranteed to give a neat and clean edge.

For example, in companies that process stones, there are special installations. Diamond drilling is done automatically, as well as water supply. This happens through the inside of the device. Thus, there is a constant cooling of the edge and cleaning of the drill. When drilling at home, you can organize a bath that will be around the hole, and thus at the same time will cool the edge. So when drilling, you only need to raise the tool so that water constantly gets into the hole and onto the edges of the drill.

When making holes in stone, it is best to set the tool to the lowest possible speed. Small size drills, which are made using diamond coating technology, should be operated at a speed of approximately 700 to 1000 revolutions per minute when drilling.

For example, crowns that were made using thermosintering technology operate at a speed that is constantly changing, depending on the diameter. Thus, for hole diameters:

At 4 millimeters, the speed should be from 1900 to 2100 rpm;
At 10 millimeters, the speed should be between 900 and 1000 rpm;
At 22 millimeters, the speed should range from 650 to 750 rpm.

Preparing to Drill a Hole

With little or no stone drilling experience, it is best to practice on some other piece of cut before starting work.

The best place to start is to markup. Pencils very often become invisible on the stone, so it is best to leave marks with masking paper tape on top of which marking will be made.

Drilling starts at a significant angle, through which a small groove is drilled. Gradually, you need to align the crown so that it acquires a vertical position, while you should not put much pressure on it. In the event that you start to put pressure on the diamond drill, while pressing it harder against the stone, the tool will begin to move and ruin the surface.

With little experience with a drill, you can spoil the polishing of the stone, since it can be very difficult to hold the tool in your hands. In this case, the edges of the hole are broken, and drilling is not carried out exactly in the intended place.

What should be laboratory furniture?

One important part of the laboratory is the furniture. Each laboratory in which chemical, biological, medical research will be carried out must have appropriate furniture. Special tables, cabinets, pedestals, tables and cabinets - all this is an integral part of the laboratory.

For a person who has practically no idea how the work process in the laboratory takes place, it is completely incomprehensible why an ordinary table or chair is not suitable for this. But in fact, furniture plays a huge role in the laboratory, which is why household furniture cannot be in the laboratory.

What are the basic rules for laboratory furniture?

The most basic rule for laboratory furniture is that it should be ergonomic and practical. Conducting experiments and research of a different nature should be carried out in a convenient and well-planned environment. Different decor in such rooms is categorically unacceptable.

The second rule says that a table or any cabinet, whether it is retractable or not, should be simple and multifunctional. For any business, there must be certain furniture that will be responsible for a particular task. For example, a drying cabinet must be used only for drying.

The third rule is: laboratory furniture in Moscow must be very strong, as it will have to withstand not simple loads. The strength of such furniture should be at the highest level, as a rule, laboratory furniture should be resistant to cracking. Often such furniture is made of durable material, such as plastic, metal or glass.

Where to buy laboratory furniture at affordable prices?

LLC "Innogen" is engaged in the sale and production of laboratory furniture. Today, the production of this company is in high demand in all CIS countries. The production facility is located on the territory of the Russian Federation, namely in the city of Pskov.

For the production of laboratory furniture, only high-quality and durable equipment for metal processing, as well as its painting, is used. It must be said that the laboratory furniture of the brand "Expert" received a quality mark, and is also fully certified according to all the requirements of GOST in Russia.

Almost every day is drilling holes in stone. And it does not cause any particular difficulties when using special equipment. But what to do if you do not have experience and knowledge, but drilling a hole is necessary.
I myself remember the first time I went to a hardware store and asked for help from a sales assistant. I needed to drill 2 small holes in a granite slab. The salesperson advised me on drills with a Pobedite tip, assuring me that they fit perfectly.
Without going into details of my first drilling holes in stone, I will only say that 3 drills that I purchased in this hardware store burned out, beat the edge of the hole being drilled, and if these holes were not technical, then it would take a long time to fix the problem.
So. How to drill a hole in a stone on your own and is it necessary for this?

Now drills have appeared on sale - diamond-coated crowns and they can be bought in almost any major construction market. The price depends on the thickness of the coating and the service life of the drill.

And if you need to drill one hole and two, then almost any will do. And if you plan to use such a tool often, then it is best to purchase a crown in which the diamond is not sprayed, but is pressed over the entire volume of the cutting edge.
Crown fastening is also different. You can use a drill or grinder. We use heavy cutters and a device for drilling holes in stone products, they have the same attachment as on a small cutter.
And now you have become the owner of a diamond-coated drill, what to do next?
How drill a hole in stone so that it is even and neat?

I think that 4 simple steps will guarantee you a long service life of diamond hole saws.

Step 1. When drilling holes in stone, use diamond drills at low speeds (rpm). Small diamond drill bits should be used at about 1-2 speeds of your tool - that's about 700 to 1000 rpm.
Diamond drills must be used at variable speeds depending on their diameter.
6mm - 2000 rpm
12mm - 950 rpm
24 mm - 700 rpm
Step 2.
Drilling holes in stone and other materials need with water. Water prevents overheating of the cutting edge of the diamond drill, washes away the sludge from its pores. This, in turn, will extend the life of the drill, protect it from jamming, and the stone itself will not overheat and the edge will remain neat.
In production, when drilling holes in stone, water is automatically supplied to the inside of the drill under pressure and the drill is constantly washed with water. doing so is not always possible. To do this, you can make a "bath" around the drilled hole.

You can cut out the middle part of a plastic bottle and stick it with tape to a stone surface, fill it with water. When drilling holes, lift the bit so that water wets the cutting edge and enters the hole to be drilled.

Step 3.
If you have little experience, before you start drilling holes in the stone, practice on some pruning.
Make a markup. Draw a line on the stone. Often, the pencil leaves practically no traces on polishing, so you can use masking paper tape and make the necessary marks on it.
First way which is often recommended for drilling holes in stone.
First, start drilling the stone at a significant angle to drill a small groove, then gradually level the bit until it is vertical, while continuing to lightly press on it. If you immediately press the diamond bit to the surface of the stone and start drilling, then the drill will not stand still, but will “roll” on the surface and spoil it.
Drills are not always well centered, and if you have little experience in drilling holes in stone, then initially you can not hold the tool and spoil the polish, break the edge of the hole being drilled, and, finally, just drill inaccurately.
There is a pretty simple second way For precise drilling of holes.
To do this, you can drill a hole in any pruning of a stone, you can say to practice.
After the hole is drilled and completely finished, it can be used as a template. Just simply attach to the product in which you need to drill a hole and clamp. Thus, the drill will move along the already drilled hole, it will not hit and your product will have a neatly drilled hole. You can also add water there.
Step 4

When purchasing a sink made of artificial stone, the buyer often encounters such a problem as the lack of a hole for the mixer. Of course, you should turn to professionals, but you can solve this issue yourself.

In order to understand how to drill an artificial stone sink , You have to figure out what it's made of. There is no clear definition of "artificial stone", so different manufacturers call this term various materials that differ in density and properties.

The most common are:

• porcelain stoneware;
• agglomerate (fragranite, silgranite and their analogues);
• acrylic stone.

When working with any of these materials has its own characteristics. To decide on that , with which drill to drill a stone sink, you must initially understand what exactly was purchased.

The photo shows a porcelain tile countertop.

Porcelain stoneware is the strongest and most durable of the above materials. He is not afraid of temperature and chemical influences, resistant to mechanical damage. It stands out by the sonorous "glassy" sound.

Other types of artificial stone produce a duller sound due to the addition of plastic and polymeric materials. Even though making a hole in other materials is easier than drilling a porcelain stoneware sink , very often the choice of clients falls on him. Given the extraordinary density of the material, conventional drills will be powerless here.

Only a crown or a drill with a carbide tip, best of all a diamond one, will cope with porcelain stoneware. Sintered ring drills will also be able to work with it, but their cost is much higher, so they are rarely chosen, only if there is a need for a large amount of work. Due to the high strength, when working with this material, it is necessary to cool the drill and the working surface with water. It is necessary to work with porcelain stoneware at minimum speed (300-400 no more).

Where to cut a hole?

Another important question that will arise regardless of what material the sink was purchased from: cut a hole in it from the front side after installation? Or do it before installation and from the back?

Each method has a number of pros and cons:

1. In the first case the edges on the front side will be much smoother, but there is a chance of spoiling the front side of the sink with a drill, and if it has a narrow rim, then splitting the edge.
2. In the second variant the risk of damaging the bowl is much lower, but there is a chance of getting a sloppy edge of the hole on the front side. In most cases, this is not critical, since the edges of the hole are closed with a mixer. When flipping, it is possible to inadvertently make a hole on the wrong side, so it is advisable to mark the side on which you want to install the faucet.

In any of the methods, it is desirable to place the hole away from the edge of the product, but at the same time, without hitting the bowl. To do this, before starting work, it is necessary to attach the lower mixer nut to the sink and mark its center.

The nuances of shells from algomerat

If you purchased a sink made of stone agglomerate, it will be a little easier to work with it.

Agglomerate shell shown

Well-known manufacturers usually attach a cutter or core, which knocks out a piece of stone that has already been drilled, but not completely. If they are absent, then it is best to use a diamond-coated cutter or crown and proceed as when working with porcelain stoneware.

A fostner cutter will also cope with a hole in a stone agglomerate product. But be prepared for the fact that after that it will need to be sharpened, or even thrown away.

Be sure to read the instructions and operating instructions before taking any action so as not to accidentally lose the product warranty.

acrylic stone

If the sink is made as one piece with the countertop and the same color with it, then this is an acrylic artificial stone. Of the above materials, this one has the lowest density, so it is easiest to work with it. If the purchased sink is made of acrylic stone, then it can be drilled or wood.

The hole for a standard mixer, in most cases, has a diameter of 35 mm. In a product made of acrylic stone, it is easily drilled with a drill bit for woodworking or a forstner cutter of the same diameter. It is necessary to work at low or medium speeds. When drilling this material, a large amount of chips are formed, and the plastic that is part of the acrylic stone emits an unpleasant odor, somewhat reminiscent of epoxy glue.

An example of a sink made from this material

Acrylic stone is the most malleable of all types of artificial stone, so most countertops are made from it. If there is a need to make a hole in it for a sink or hob, it is better to pre-practice in the middle of the cut-out part so as not to spoil the entire countertop. Despite the fact that the acrylic stone is sawn without any problems with a jigsaw, it is undesirable to cut it with it. When working with a jigsaw, so-called stress concentrators (sharp transitions, sharp corners, microcracks) often occur, which will affect the service life of the product.

If you think about it , how to drill a stone countertop, then the best option would be - a milling cutter, but it is not always available.

In this case, it is permissible to cut a hole smaller than necessary by 5 mm with a jigsaw. After the work with a jigsaw is finished, bring it to a clean size with a cutter. Be sure to make an R3 chamfer along the edges, it will also reduce stress and increase the life of the countertop.
