The HSS sheet metal hole cutter drills large holes with high precision. The self-centering drill tip with a cross-cut design allows for perfect centering without wandering when drilling materials of low thickness. The precision-ground drill features a straight flute for smooth drilling with high cutting power. This product enables the drilling of large holes in thin materials such as metal sheets, profiles, pipes, and other materials without pre-drilling. It is also ideal for deburring and enlarging already drilled holes without cold welding. It is used for non-ferrous metals, steel sheets, and plastics. The countersink has a hexagonal shank (1/4 inch) for high power transmission and quick bit changes.
