3M 7000120702 Deburring Disc 4 in Very Coarse Silicon Carbide

Product Description

The 3M 7000120702 is a silicon carbide deburring disc designed for aggressive material removal on metal workpieces. At 4 inches in diameter with a 1/4-inch shank mount and 1/2-inch center hole, this disc attaches directly to compatible rotary tools and die grinders. Rated to 8,000 RPM maximum, it handles very coarse deburring, edge blending, and surface preparation tasks. Silicon carbide abrasive cuts hard materials efficiently and holds up under repeated use. The black disc construction is standard for this abrasive type. Machinists, pipefitters, and fabrication techs keep this disc on hand for fast deburring work on ferrous and non-ferrous parts.

This disc is suited for bench-top rotary tools, die grinders, and similar shank-drive equipment used in machine shops, fabrication facilities, and pipe trades. It handles deburring on cut pipe ends, drilled holes, stamped sheet metal edges, and cast parts. The very coarse grade makes it most effective for fast stock removal and aggressive edge cleanup rather than fine finishing work. It is a single-unit item appropriate for both job-site and shop use where occasional deburring tasks arise.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotary abrasive tools. Verify the tool spindle speed does not exceed the 8,000 RPM maximum rating of this disc before mounting. Disconnect power or air supply to the tool before installing or changing the disc. Always wear appropriate eye protection and follow applicable shop safety standards when operating abrasive discs at speed.
