The diamond-grit edge on these hole saws cuts more accurately, leaves a smoother finish, and lasts up to twice as long as carbide-grit-coated teeth. Saws are for use on reinforced plastic, Kevlar, stone, brick, and other abrasive materials with high silicon content. Attach them to a drill or drill press. An arbor with pilot drill (sold separately) is required. To cut ceramic tile, you must use a 1/4" carbide-tipped pilot drill.

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.
