Depending upon their resistance to scratching and cracking, tiles are classified into five different classes. Class 1 tiles are very much prone to scratches and cracks and hence are not recommended to be used in flooring; they are only used on the walls. On the other hand, tiles of the class 5 categories are the most resistant to scratches and cracks and people can use such tiles in public places such as malls, shops, hospitals, religious buildings and other commercial buildings. Porcelain tiles belong to the class 4 category and hence possess high resistance to scratches and cracks, this means that they are harder to drill a hole through and for this exact purpose; you can use porcelain drill bits. These drill bits have tips that are made using an alloy of Tungsten and Carbide. Tungsten as we know is used in incandescent light bulb filament due to the fact that it has the highest melting point and the lowest thermal expansion of any other metal known to mankind. These two metals make a porcelain drill bit perfect to drill holes through Porcelain tiles without causing too much vibration and you do not need to deal with dust.
Manufacturing of Porcelain Drill Bits
The body of porcelain drill bits is made of the same material as every other type of drill bit i.e. High-speed steel, but the tip of the same is made out of an alloy of Tungsten and Carbide. It is the combination of properties of these two metals that allow the porcelain drill bit to drill perfect and smooth holes through a class 4 category Porcelain tile. If any other drill bit is used to drill holes in Porcelain tiles, for example, a carbide masonry drill bit, it can damage the tiles and drill machines.
Distinguishing Features of a Porcelain Drill Bit
Unlike conventional drill bits, the construction and working of porcelain drill bits are quite different and this is why they are able to make clear-cut holes through porcelain tiles which belong to the class 4 category.
Some of the Features of the Porcelain Tiles Drill Bit Are:
It is a multipurpose drill bit i.e. it can be used on both porcelain and masonry surfaces. So you do not need to buy a separate drill bit for your concreting project.
It has a much longer life than any other conventional drill bit, almost 3 times more.
In a single use, it can consecutively drill more than 10 holes.
On average, it can drill a hole in less than 30 seconds which is twice as fast as any other drill bit available on the market.
The holes made by it, unlike regular drill bits, are much more smooth and clean. This preserves the overall look of the tiles and is also efficient in the long run.
Its tip is made from Tungsten-Carbide alloy which gives it that extra smoothness when it comes to drilling holes in porcelain tiles.
Conclusion
What makes a skilled workman is a knowledge he possesses about the different hand and power tools he uses in his daily projects. With the wrong tool, you can never perform the right task and such is the case with drilling machines, without the knowledge of correct drill bits, the simple task of drilling a hole becomes a lot more cumbersome. This is why porcelain drill bits are specially manufactured drill bits that are used to make perfect smooth holes through the class 5 category porcelain tiles. These are specially made using an alloy of Tungsten and Carbide which makes drilling holes through porcelain and masonry surfaces much earlier and quicker.
