3M 7010309485 Deburring Disc 4 in Very Coarse Silicon Carbide

Product Description

The 3M 7010309485 is a silicon carbide deburring disc designed for aggressive material removal on metal workpieces. Measuring 4 inches in diameter with a 3/8-inch center arbor hole, this disc mounts directly to compatible right-angle grinders and deburring tools. The very coarse grade silicon carbide abrasive cuts fast on ferrous and non-ferrous metals, making it well suited for removing burrs, flash, and sharp edges left after cutting, stamping, or machining operations. Rated to 6,000 RPM maximum, it delivers consistent performance at typical grinder operating speeds. The disc weighs approximately 2.39 pounds per packaged unit.

This deburring disc is used in fabrication shops, maintenance facilities, and field service settings where fast edge conditioning is required. It is appropriate for use on steel, aluminum, and other metals encountered in HVAC equipment fabrication, plumbing rough-in work, and general industrial maintenance. Technicians and fabricators reach for this disc when cleaning up cut pipe ends, sheet metal edges, or machined parts prior to assembly or finishing.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive disc safety procedures. Ensure the tool is powered off and unplugged before mounting or removing the disc. Verify the tool's rated RPM meets or exceeds the disc's 6,000 RPM maximum before operation. Always inspect the disc for damage before use and follow applicable ANSI B7.1 safety standards for grinding wheel and disc operation.
