Lateral recess for easy removal of the drill core. Designed for dry use, no extra cooling required. In the case of successive borings, it is recommended to cool the crown briefly with water after every hole. The useful length is the strength of the tile/porcelain/granite slab . Usually max. 2 cm. Granite plates/countertops can be drilled up to 5 cm. The crown should be pulled out of the borehole several times, so that it cools down briefly! Important: Do not drill into the surface if the material is laid.
