3M 7100020897 Deburring Disc 7 in Very Coarse Silicon Carbide

Product Description

The 3M 7100020897 is a silicon carbide deburring disc designed for aggressive material removal on metal, composites, and similar workpieces. The disc measures 7 inches in diameter with a 7/8 inch center arbor hole for mounting on standard angle grinders and disc grinders. Rated at a maximum of 3,300 RPM, it carries a Very Coarse grade designation suited for rapid deburring, surface conditioning, and edge cleanup. Silicon carbide abrasive delivers sharp, consistent cutting action on hard or brittle materials. Machinists, fabricators, and maintenance technicians use this disc in production and repair environments where controlled, fast stock removal is required.

This deburring disc is used in metal fabrication shops, maintenance facilities, and manufacturing environments where burrs, sharp edges, and surface scale need to be removed quickly. It mounts via a standard arbor connection and is compatible with disc grinders and angle grinders that accept a 7 inch disc with a 7/8 inch arbor hole. Typical applications include post-cut deburring on steel, cast iron, and similar hard materials. The Very Coarse grade makes it best suited for initial deburring passes rather than finish work.

Key Features

• 7 inch diameter disc with 7/8 inch center arbor hole for standard grinder compatibility
• Silicon carbide abrasive provides sharp, fast cutting on hard and brittle materials
• Very Coarse grade for aggressive deburring and edge conditioning
• Maximum operating speed of 3,300 RPM

Compatibility

Designed for use with disc grinders and angle grinders that accept a 7 inch diameter disc mounted via a standard 7/8 inch arbor connection.

Installation Notes

Installation and operation should be performed by trained machinists or fabricators familiar with abrasive disc safety. Always power down and isolate the grinder before mounting or removing the disc. Verify the tool spindle speed does not exceed the disc maximum rating of 3,300 RPM before operation. Inspect the disc for damage before each use and follow all applicable ANSI abrasive safety standards.
