Fast-Cut Hole Saw Kits

Quickly cut perfectly round holes in multiple sizes—these kits come with at least six hole saws in different diameters. Their specially designed teeth cut through wood, sheet metal, and other materials faster than the teeth on standard hole saws. Made with high-speed steel teeth and a steel body, they’re often called bimetal hole saws. Unlike drills, these saws make circular cuts without cutting up the material of the core. Use them to cut large holes, such as a cutout in a door for a doorknob. Attach them to a drill or drill press with the included arbors.

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.

Variable Set Tooth Style		Arbor with Pilot Drill

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

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

Variable Set Tooth Style

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.

Fast-Cut Hole Saws


	Arbor with Pilot Drill

Specially designed teeth cut faster than the teeth on standard hole saws. Teeth are high-speed steel for cutting wood, plastic, and metal such as aluminum, brass, steel, and stainless steel. Attach saws to a drill or drill press. An arbor with pilot drill (sold separately) is required.

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.
