3M 7010364779 Deburring Disc 6 in Very Coarse Silicon Carbide

Product Description

The 3M 7010364779 is a silicon carbide deburring disc designed for aggressive material removal on metal, plastic, and composite surfaces. At 6 inches in diameter with a 7/8-inch center arbor hole, it mounts to standard angle grinders and finishing tools. Rated to 4000 RPM, this disc is graded Very Coarse, making it well suited for heavy burr removal, edge cleanup, and surface conditioning where fast stock removal is the priority. Metal fabricators, pipefitters, and maintenance mechanics are the primary installers and users of this disc in shop and field applications.

This deburring disc is used in metal fabrication shops, pipe prep work, and general industrial maintenance. It performs well on ferrous and non-ferrous metals where sharp edges, flash, or weld spatter need to be removed quickly before the next operation. The arbor-style connection makes mounting straightforward on compatible grinders and disc pads. Its Very Coarse grade is best applied where surface finish is secondary to material removal rate.

Installation Notes

Installation should be performed by qualified personnel familiar with angle grinder safety practices. Always power down and disconnect the tool before mounting or removing the disc. Verify the tool's maximum RPM rating meets or exceeds the disc's 4000 RPM limit before use. Wear appropriate PPE including eye protection and gloves during operation and disc changes.
