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.

Long-Life Hole Saws

With carbide teeth—the hardest in our hole saw offering—these hole saws cut through harder materials and stay sharp for up to twice as long as saws with high-speed steel teeth. All require an arbor (sold separately). Use them in drills and drill presses to create perfectly round holes, such as enclosure cut-outs for cable to pass through.

Long-Life Fast-Cut Hole Saws for Wood and Plastic


	Arbor with Pilot Drill	Quick-Change Arbor with Pilot Drill Bit	Replacement Pilot Drill Bit

Cut holes in wood and plastic five times faster than standard hole saws and with fewer blade changes. The teeth on these saws are shaped to power through not only wood, particleboard, and plastic but also drywall, plaster, and even masonry. Made of carbide, the teeth are the hardest in our hole saw offering, so they stay sharp up to twice as long as high-speed steel teeth.

To attach these saws to a drill or drill press, you'll need an arbor with a pilot drill bit (sold separately). If you're using an arbor you already have, make sure the pilot drill bit is at least 3 _5/8" long.

Quick-change arbors don’t require an L-key or screwdriver to swap out a dull pilot drill bit—just pull back on the release collar.
