Hole Saws

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.

1 9/16" Cutting Depth


Variable Set Tooth Style		Arbor with Pilot Drill

Unthreaded Arbor Hole—Unthreaded hole saws attach and detach from compatible arbors more quickly than threaded hole saws. Use a simple push-and-turn motion to attach and detach the saw, instead of having to thread it on and off.

Variable-Set Tooth—Saws with variable-set teeth make faster cuts with less vibration than saws with constant-set teeth.

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.

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.
