Returns Simplified.100% faster: Core hole drills have a significantly shorter drilling time than twist drills due to their cutting behavior. Core hole drills only machine the tooth width, the drill core is ejected. With twist drills, the entire drill core is machined, so the required force and drive power must be very high. 30% more effective: Core hole drills ensure circular and burr-free cutting results, especially with thin materials. Larger drill diameters can be drilled precisely with less force. Longer service life: the cutting edges of the core hole drill need to be sharpened less often than the cutting edges of a twist drill. The 6 mm thick drill body and the optimized cutting geometry ensure high stability. Thick-walled core hole drill for a longer service life. With 19 mm standard Weldon holder
