Malco's sheet metal hole cutter quickly installs into the chuck of any corded or cordless drill as small as 1/4" (6.35 mm). The Distinctive Gold Bits, Bearings, and Pivot Pin signify the longest lasting, fastest cutting, and easiest adjusting solution for cutting holes in sheet metal. A Lightweight aluminum frame makes these accessories extremely portable for a variety of hole cutting applications in sheet metal, which includes 20-gauge (1.02 mm) galvanized steel. The larger HC2 model cuts 2 to 20" (51 to 508 mm) holes.
Both the HC1 and HC2 sheet metal hole cutter feature Malco's "Gold Standard" Cutter Bits. These cutter bits feature a long lasting, mill type cutting edge and large flat for adjusting the cutting edge location up or down to extend bit life. The CB cutter bit fits either model and is easily replaceable.
