Hole Saws for Sheet Metal

1/4"-1/2" Cut Depth Saw

Arbor with Pilot Drill

Arbor with Spring-Loaded Pilot Pin

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.
