Set consisting of: 1 each of Ø 6 mm, 8 mm, 14 mm, 35 mm, 40 mm, 50 mm, 68 mm. M14 thread for use on angle grinders. Long lifespan and fast drilling progress due to vacuum-brazed diamonds. Easy removal of the core through lateral cutouts. No extra cooling required. Ø 6-14 mm also feature an integrated paraffin emulsion for better cooling. For consecutive drilling, it is recommended to briefly cool the crown with water after each hole. The recommended usable length is the thickness of the tile, porcelain stoneware, or granite slab, usually a maximum of 2 cm. Granite slabs or countertops can be drilled up to 5 cm. In this case, the crown should be pulled out of the hole more frequently to allow for brief cooling. Important: Do not drill into the substrate when the material is laid. Maximum working speed: 80 m/s.
