Long service life and fast drilling progress thanks to vacuum hard soldered diamonds
Easy removal of the drill core thanks to lateral recesses
No extra cooling required. . For Ø 6-14 mm an additional paraffin emulsion is integrated for improved cooling. We commend to briefly cool the tip with water in case of drilling in quick succession!
We recommend using the thickness of the tile / fine earthenware / granite board as useful length. As a rule, max. 2 cm granite boards / work boards up to 5 cm can be drilled. Retract the drill bit often from the drilled hole so that it can cool down!
Important: Do not drill into the subsurface in case of laid material!
