3M 7000120747 Deburring Wheel 12 Inch Silicon Carbide

Product Description

The 3M 7000120747 is a 12-inch diameter unitized deburring wheel designed for edge blending, surface conditioning, and deburring on metal workpieces. Built with silicon carbide abrasive at a fine grade and density 2 (soft), it delivers consistent, controlled material removal without aggressive stock loss. The 1/2-inch face width and 1-1/4-inch center hole suit standard arbor mounting on a range of stationary and handheld grinding equipment. This wheel is rated to a maximum of 2,600 RPM. It is installed and used by machinists, metalworkers, and fabrication shop technicians performing finishing and deburring operations.

This wheel is suited for light deburring, blending, and finishing applications in both production and job-shop environments. Its soft density and fine silicon carbide construction make it appropriate for work on ferrous and non-ferrous metals where surface finish quality matters. Compatible tooling includes centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. The unitized construction maintains consistent performance as the wheel wears down over its service life.

Compatibility

Compatible tooling includes centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. The 1-1/4-inch center hole fits standard arbors on equipment designed for 12-inch unitized wheels.

Installation Notes

Installation should be performed by a qualified operator following the equipment manufacturer's mounting instructions. Inspect the wheel for damage before mounting and ensure the arbor speed does not exceed the 2,600 RPM maximum rating. Always power down and lock out the machine before mounting or removing the wheel. Wear appropriate eye and face protection during operation.
