Bsc Preferred QJDIB-M-002 Hex Shank Hole Saw Mandrel

Product Description

The BSC PREFERRED QJDIB-M-002 is a hex shank hole saw mandrel built for use with hole saws measuring 1-1/4 inches and larger. The 7/16-inch hex shank design reduces slippage between the mandrel and the chuck, delivering more consistent torque transfer during heavy drilling operations. This mandrel is a supporting accessory used in conjunction with hole saw blades to cut circular openings through wood, metal, drywall, and similar materials. Electricians, plumbers, and HVAC technicians routinely use hole saw mandrels when running conduit, pipe, or ductwork through framing and structural materials. Its construction is suited to demanding jobsite conditions where secure chuck engagement is critical.

The QJDIB-M-002 is appropriate for residential and light commercial applications where hole saws 1-1/4 inches and larger are required. Typical use cases include boring through wall plates and floor joists for pipe or conduit runs, cutting access holes in sheet metal enclosures, and general rough-in work across multiple trades. The hex shank profile is compatible with standard 3-jaw drill chucks and impact-rated drivers that accept hex shank accessories.
