OK-Line Diamantbohrer Ø5mm OKLINE

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 RPM.

2. Slowly raise the drill while applying pressure to the corner of the material.

3. While drilling, gently "stir" - this promotes material removal, distributes the work across the entire diamond surface (longer lifespan: approximately 20 holes), and slightly enlarges the hole (this prevents stress cracks when subsequently drilling with a hammer drill).

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