For dry use on stone slabs, marble, granite, ceramic tiles, and porcelain stoneware, with a wax core (10 mm) for optimal cooling.

Speed range: 1500-6800 RPM (the faster, the better).

Application:
1. Start at a 45° angle with high speed.
2. Gradually straighten up while applying pressure on the corner of the material.
3. While drilling, lightly "stir" - this promotes material removal, distributes the work across the entire diamond surface (longer lifespan: lifespan approximately for 20 holes) and makes the hole slightly larger (this prevents stress cracks during subsequent drilling with a hammer drill).

The diamond drill is only used to drill through the surface material. The hole in concrete or brick should then be finished with a standard carbide drill and hammer drill.

Contents: 1 diamond drill each of ø 5, 6, 8, 10, 12 mm, in a plastic box.
