Cold Saw Blades for Steel and Cast Iron


	Round Arbor

Blades and teeth are steel and treated to a Rockwell Hardness between C63 and C65 for increased wear resistance when cutting through steel and cast iron bars, rods, pipe, and tubing. Choose blades with more teeth for a smoother cut.

High-Speed Steel Slitting Saws

These general purpose saws are good for cutoff, slitting, and slotting applications in a wide range of materials, including aluminum, iron, and steel. Use with an arbor (sold separately).

Saws with a 2 _3/4" mill dia. are also known as screw slotting saws. Saws with 1 _1/4"-2 _1/2" and 3"-8" mill dia. are also known as plain metal slitting saws.

Circular Saw Blades for Aluminum


	Round Arbor

Teeth are carbide tipped and designed to push chips away from the blade to prevent clogging and produce smooth cuts in aluminum sheets, tubing, and T-slotted framing. Choose blades with more teeth for a smoother cut. Blades with a narrower width of cut make faster cuts with less material loss.

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.

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.
