MILWAUKEE Core drill 39X50 mm HSS LONG 4932371766

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