Diamond Core Drill Bit Set "Dry", 4-piece, M 14

M 14 thread for use on angle grinders. Long lifespan and fast drilling progress due to vacuum-brazed diamonds. Easy removal of the core thanks to side cutouts. No extra cooling required. Diameters of 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 drilling.

The recommended usable length is the thickness of the tile, porcelain stoneware, or granite slab, typically 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.
