Malco HC2 Adjustable Hole Cutter Range

The Malco HC2 adjustable hole cutter covers diameters from 2 in to 20 in for sheet metal and HVAC work. High speed steel teeth provide clean cuts up to 1 1/8 in deep. A 1/4 in thread mounts the cutter on compatible arbors. The pilot drill measures 7/16 in dia for accurate hole starts.

Sheet Metal Workers and HVAC Installers

Tradespeople who need variable hole sizes without swapping multiple fixed saws benefit from the adjustable design. The tool cuts metal ductwork and panels efficiently. Buyers who want more storage for a full kit of individual saws or prefer a self-contained arbor should look at something else.

1/4 In Thread and 7/16 In Pilot Drill Compatibility

The cutter requires an arbor with a 1/4 in thread and accepts a 7/16 in pilot drill, both sold separately. Matching these two specifications to your existing equipment decides whether this is the right part.
