Hole Saw Kits for Sheet Metal

Lower cutting depths than standard hole saws make these saws less likely to rip or tear while making smooth, burr-free cuts in sheets. All saws are made entirely of heat-treated high-speed steel for cutting aluminum, brass, bronze, and steel. Attach hole saws to a drill or drill press with the included arbors.

Hole Saws for Sheet Metal

Lower cutting depths than standard hole saws make these saws less likely to rip or tear while making smooth, burr-free cuts in sheets. Heat-treated high-speed steel teeth cut through aluminum, brass, bronze, and steel. Use these saws on a drill or drill press. An arbor (sold separately) is required.

Arbors with pilot drill guide your cut.

Arbors with spring-loaded pilot pins push out the slug as you cut. They require a drilled pilot hole.
