Our hole-puncher for diameters between 12,7 mm and 63,5 mm. The burrfree alternative to a metal saw or to a metal coredrill is punching holes into control cabinets or steel sheets with a thickness up to 3,0 mm (19,0 mm ; ¾“ screw or draw bolt) and up to 2,0 mm (9,5 mm; 3/8“ screw or draw bolt). Due to the ball bearing, cabinet manufacturers benefit from 30% force saving.
