Extraordinary lifetime and high drilling speed in concrete and concrete with rebars; New centric conical tip - top hole guidance, constant hole diameter; New Sharp cutting edge border - deep penetration into concrete with rebars with each hit - continuous high drill speed. New wear mark - always correct hole diameter for anchor setting. Full head carbide tip lasts longer for faster drilling speed and less carbide wear; the centric conical tip guides bit through concrete, provides rounder holes. Wear mark alerts the user when bit has worn to a level inappropriate for precision anchoring.
