Easy Core quick-release hole saws. Shatterproof bi-metal construction with ten-degree positive teeth for aggressive, smooth cutting in steel, stainless, wood, plastic and pipe. Quick-release arbor and open-back design provide fast size changes and rapid core ejection for improved productivity.

Carbide-tipped hole saws engineered for dramatically longer life and faster, cleaner cutting across a wide range of materials, with improved tooth geometry and an aggressive 10° positive tooth angle for smooth cutting. A three-pin quick-release arbor makes size changes fast, while the open-back design enables core ejection up to five times faster by pushing out the slug with the pilot bit. Provides a deeper 2-3/8" depth of cut for increased capacity in thicker materials.

Quick-change impact hole saws with integrated 1/4" hex arbors for fast attachment to impact drivers. Spring-loaded pilot drill enables quick slug removal and the bi-metal teeth cut clean holes in sheet metal. Ideal for electrical boxes and control panels.
