Side cutouts for easy removal of the core. Designed for dry use, no additional cooling required. For diameters of 6-14 mm, a paraffin emulsion is additionally integrated into the drill bit for better cooling. For consecutive drilling, it is recommended to briefly cool the crown with water after each drilling. The recommended working 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.
