Drill bits and dry drill bits are indispensable tools for the tiler and natural stone installer. Especially the use of extremely hard materials, such as porcelain stoneware, which is not only used on the floor but also in the wall area, requires high-quality drill bits. Tilers and installers use drill bits and dry drill bits to make holes for water connections, drains, sockets and for shower enclosures or sanitary attachments.
Diamond wet drill bits can be mounted in the drill stand or used as drills with wet drilling attachment (water flushing bush). The Dahm drill stand KDB-200 (Art.: 40103) offers the optimal conditions for an exact and fast drilling. The material is fixed exactly and the water supply by a water pump ensures maximum cooling. Particularly thin-walled drill bits with high cutting speed and high cutting quality are used (Dahm Art.: 50190/50100). These drill bits can, of course, also be used in a drilling machine, in which case they are drilled with a drilling jig. Karl Dahm offers several systems for freehand drilling, the installation set (Art.: 55310) or the water pressure tank with flushing bush (Art.: 50316). For safety reasons, a personnel safety switch (Art.: 21134) must always be used for wet drilling, if not already present on the drive unit. Compared to dry core bits, wet core bits have a considerably longer service life. A further advantage is the dust binding, especially when working in inhabited rooms. In the last few years, diamond dry core bits have also gained acceptance among tilers, drilling is possible without any major technical effort.
The dry core bits are mounted on an angle grinder, placed at an angle on the material and guided into the material with a slight wobbling motion. Diamond dry core bits must never be laid flat, otherwise the cooling is impaired and the service life is reduced. Dry core bits with small diameters (6-14mm) have additional paraffin in the shaft, this paraffin liquefies during drilling and provides better cooling. In general, the larger the diameter of the dry core bit, the better the cooling and thus the service life. The service life can be strongly influenced by correct handling. Diamond dry core bits are used at a speed of approx. 10000 rpm, do not apply too much pressure. Karl Dahm offers high-quality diamond dry core bits from 6- 100mm or complete sets (Dahm-Art.: 50235). The diameters 6-12mm are also offered with shaft adapter for use in cordless screwdrivers (Dahm-Art.: 50230-50233). No matter if wet or dry drilling is chosen, the quality of the used drill bits is decisive. Only high quality drill bits guarantee a good tool life and cutting quality and ensure satisfaction of user and customer.
Among the useful diamond tools are the drill bits. With them you can drill tiles or drill porcelain stoneware. Which work can be carried out with these useful tools and what you have to pay attention to, you will find out in detail below.
In contrast to conventional drills, the crowns are suitable for making larger holes. Therefore, the diamond core bits have diameters of about 20 to 68 millimeters. These are suitable for the following applications:
Since different drill diameters are usually involved, it is worthwhile to buy a diamond core bit set. These sets are equipped with different crowns. Therefore it can be selected according to the respective requirements. The purchase of a complete set is also cheaper than buying individual tools of this type.
It is advantageous that the crowns are provided with an M14 thread. This allows them to be mounted on any angle grinder. These tools are also equipped with an M14 mount. Therefore, no additional power tools are required to use these diamond tools. An angle grinder, which is often referred to as a flex, is available anyway at every tiler and other craftsmen working in this branch.
The drill bit is simply screwed onto the thread holder and tightened. The work can already begin. What needs to be observed during the work is described below.
After marking where a hole is required, all that remains is to hold the crown directly on it. After switching on the angle grinder, only a small amount of pressure needs to be applied. Then the crown will slowly eat through the tile. Drill holes up to 35 millimetres deep can be made without any problems.
If sparks occur during drilling, it is essential to reduce the pressure slightly. Otherwise there is a risk of overheating. Under certain circumstances this could lead to damage to the crown. At the very least, however, wear will increase. It is also very important to wear safety glasses when working.
The diamond tools for making larger holes are also available for wet cutting. These are available in sizes between 20 and 100 millimeters. They can be used either with a drill or a cordless screwdriver. However, the tools must be equipped with a water connection. When cutting tiles with a wet drill bit, there is little heat development. Dust formation is also reduced. Nevertheless, suitable safety glasses should also be worn when working. Anyone who wants to drill into porcelain stoneware can do so at a depth of up to 60 millimetres.
Diamond-tipped drill bits are therefore available for numerous different applications. That is why such diamond tools are indispensable helpers for every tiling job. At Karl Dahm, these high-quality tools for tile drilling or porcelain stoneware drilling are available at a particularly good price-performance ratio.
