Starrett 56763 Hole Saw Arbor Straight Hex Shank

Product Description

The STARRETT 56763 is a hole saw arbor designed to connect compatible hole saws to a drill or drill press for clean, accurate cuts through a wide range of materials. The arbor features a straight hex shank measuring 11/32 inches, an integral carbide tipped pilot drill, and a threaded shank attachment method that locks securely to the saw body. The stainless steel arbor construction resists corrosion and handles the torque demands of repetitive production or service cutting. At 0.5 pounds, the 56763 is a compact, tool-bag-ready component for electricians, plumbers, HVAC installers, and general contractors who depend on hole saws daily.

The 56763 suits applications where SH, DH, CT, and D series hole saws are used for cutting conduit knockouts, pipe penetrations, duct openings, and similar through-holes in residential and light commercial work. The minimum compatible tool diameter is 1-1/4 inches, making it appropriate for a broad range of standard hole saw sizes. The carbide tipped pilot drill maintains center position through the cut and holds up under repeated use without frequent resharpening.

Installation Notes

Installation is typically performed by electricians, plumbers, or HVAC technicians using a standard drill or drill press. Ensure the drill is powered off and the chuck is fully released before threading the hole saw onto the arbor. Thread the hole saw body fully onto the arbor until snug and verify the pilot drill is properly seated and centered before beginning the cut. Follow all applicable safety guidelines for rotary cutting tools on the job site.
