Hole Cutters and Cutter Bits
Distinctive gold Bits, Bearings and Pivot Pin signify the longest lasting, fastest cutting, easiest adjusting solution for cutting holes in sheet metal.
Malco Hole Cutters quickly install into the chuck of any corded or cordless drill as small as 1/4” (6.4 mm). Lightweight aluminum frames make
these accessories extremely portable for a variety of hole cutting applications in sheet metal including 20-gauge (1.02 mm) galvanized steel. A
compact model HC1 Hole Cutter is adjustable for making 2 to 12” (51 to 305 mm) diameter holes. The larger HC2 model cuts 2 to 20” (51 to 508
mm) holes. A combination English/Metric diameter gauge is included on the adjustable pivot slide for both models and both models use the same
mill-type Cutter Bit and replacement parts.
