If you use a Malco HC1 or HC2 hole cutter for sheet metal work, these replacement bits are a must-have.

You get two in a pack, and they're the real deal—gold coated for longer life and faster cutting.

They're designed to fit right into the chuck of any standard drill (even a 1/4-inch one) and are built to handle cutting clean holes in sheet metal up to 22-gauge thick.

The sealed bearings and easy-adjust pivot pin make them smooth and simple to use.

When your old bit gets dull, just swap it out and you're back in business.

Perfect for HVAC, metal fabrication, or any DIY project involving ductwork or thin metal.

Keep your hole cutter performing like new.
