Arbor with
Pilot
Drill Bit

These standard saws have high-speed steel teeth to make circular cuts in wood, plastic, and metal. Often used to remove more material than drill bits, they help with tasks such as creating cutouts for doorknobs or cables. Attach them to a drill or drill press. An arbor with pilot drill (sold separately) is required.

Saws with a steel body are also known as bimetal blades.

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.
