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.
The HC1 and HC2 sheet metal hole cutters 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. One cutter bit fits either model and is easily replaceable. These bits are available in 1 pack (#CB), 6 pack (#CBB), and bulk pack (#CB100).
