3M 05726 Deburring Wheel Mandrel 0.25 Inch Shank

Product Description

The 3M 05726 is a mandrel designed to mount and drive unitized deburring wheels in portable and bench-mounted rotary tools. It features a 0.25 inch shank diameter that fits standard chuck sizes commonly used in die grinders and drill presses. Rated to 35,200 RPM, the 05726 is built for high-speed deburring, edge blending, and surface conditioning tasks on metal components. Fabricators, pipefitters, and machinists use this mandrel when working with 3M unitized wheels to remove burrs and sharp edges from drilled, cut, or machined parts.

This mandrel is suited for light to medium deburring work in fabrication shops, plumbing rough-in, and mechanical assembly environments. It is compatible with unitized deburring wheels measuring 1 inch in diameter by 1 inch wide with a 3/16 inch center hole. It mounts in any rotary tool or die grinder fitted with a standard 0.25 inch collet or chuck. The compact form factor makes it practical for in-place deburring on pipe ends, fittings, and machined housings.
