Also here the application with the angle grinder art. 40253 is perfect. You can drill holes quickly and precisely - ideally without water cooling in materials such as porcelain stoneware, marble or granite.

In our Karl Dahm assortment we also have diamond drill bits for you, with which you can drill both dry and wet. These are our drill bits with bit holder. Here we also offer you different diameters:

These drill bits can be used with any cordless screwdriver. In addition to the bit holder, they also have a paraffin cooling system. Therefore our cooling gel, art. no. 50364 can also be used with these diamond core bits. The cooling gel serves for dust-free drilling with diamond core bits. The cooling gel suppresses the spread of dust and cools the dry core bits during drilling. Furthermore, the cooling gel can also be used in the wall area due to its viscous consistency. It is easy to remove and cools the dry core bits effectively.

Some of the drill bits can be used with our drill stand KDB-200, art. no. 40103. With this sturdily constructed drill stand you can drill holes precisely into the hardest materials such as porcelain stoneware and natural stone with very little effort. The device is used for wet cutting. Due to the integrated pump, the drill bit can be continuously supplied with water. Series drillings are therefore particularly suitable. As the drill stand can be separated from the water tray, the drill stand can also be placed directly on the material and easily transported. The transport handles also make it easy to transport. The speed is infinitely variable by means of the adjusting wheel, the speed constant control is electronic. The power consumption of the drill rig is 1150 W, the nominal voltage 230 V. The nominal speed is 250 to 1000 revolutions per minute. The weight of this machine is 20.9 kilos and the drilling range is 6 - 120 mm. You can use all wet drill bits with the Karl Dahm drill stand 200.
