Keramo extreme’s patented tungsten carbide tip with centre cutting geometry allows precise placement and accurate holes without chipping. ALPEN-MAYKESTAG says that it can be used on the hardest porcelain/gres tiles up to Mohs/Ritz hardness grade 9, as well as glass and porcelain. No cooling is required making the drill bit easier to handle and it can be used in all standard drills.
The Keramo extreme offers high stability due to a reinforced shank diameter and also includes a special ground tip that enables low-wear drilling and very long service life of the bit. Keramo extreme also includes a white ring mark, which signifies to the operator the ideal drilling depth.
