Among modern cladding materials granite stands out strength and durability.These qualities cause it some problems during installation.In particular, it can cause serious problems drilling in stoneware tiles. The drilling granite and how to carry out the drilling process - these two issues addressed in this article. Because the hardness and brittleness of porcelain involves selecting a special tool to address this challenge.

Tools for drilling porcelain

To date, drill holes in the ceramic and stoneware tiles are three types of tools: diamond core, and two types of diamond drill bits.Let's summarize each type of instrument and to determine how suitable for this purpose, diamond drill bits and how should be drilled granite.

for drilling holes in porcelain stoneware is of

ten used diamond crowns with galvanic coating.Low cost - their main advantage.

They reduce mechanical pressure during drilling, and also provide the opportunity to significantly increase the speed of the process.The main drawback of crowns - a little endurance.Porcelain tiles from 8mm thick one such crown can be drilled no more than five times.

ring Sintered diamond drill can be successfully used for drilling porcelain, although often they are used for drilling of concrete and similar durable material.The thickness of the working part of the drill is about 2 mm.Use these drills infrequent due to the high mechanical pressure.The disadvantage of these is also a low speed drill: single hole goes 3-5 minutes.Despite the shortcomings, ring diamond drills have a serious advantage: their service life is significantly longer than that of crown and more than 100 holes for a drill.

In general I think it is now clear what drill stoneware tiles, now let's talk about how to carry out the process of drilling.If you are interested in what are the types of drills to work with different materials, see the article: Types of drills - select tool for drilling metal, wood, concrete and tile.

How to drill granite: practical advice

drilling granite should be only from the front.To save the resource drill holes are sometimes drilled approximately 2/3 the thickness of the tile, and then the thickness of the part that is not dosverlena, knocked a sharp blow.Wherein the rear side edge chipping often occur openings.To ensure that they are hidden, tiles should only be drilled from the front side.

For drilling ceramic granite tile is better to use a special drilling machine or drelnoy bar.This not only lengthens the service life of the drill, but also simplifies and bore makes smooth and neat.Drill two-speed should be used as drilling diamond drill porcelain high speed rotation is required.Do not use a hammer drill as a drill strikes stoneware tiles can be simply split.

Before drill granite , do not forget to put under a fiberboard or plywood to make sure we do not damage the surface of the drill.The drill should be directed vertically.Do not let the process work Slick strong inclination of the drill against the tile.

This is a common mistake often leads to the destruction of the tiles or the failure of the drill.

Diamond drills during hot and should be cooled to protect against the formation of cracks and destruction.This problem is solved by applying a cooling liquid (water) during the drilling operation to drill directly.In addition, to prevent heating should be run at medium speed.

When cutting porcelain tiles used in an industrial environment of constant coolant.At home, cool the drill bit can be plain water from a plastic bottle.The bottle cap is possible to make some small holes through which water is supplied to the drill bit.You can do it even easier: to cool the drill bit with the help of pre-moistened sponge thoroughly.

Cooling drill using a dampened sponge.

If drilling is correct, tiles fall neatly drilled its part, repeats the drill diameter.Not a problem if the back of the tile appeared on small chips: they will be filled with glue, and it will not affect the quality of the tile.
