3M 7010300659 Deburring Disc 2 in Very Coarse Silicon Carbide

Product Description

The 3M 7010300659 is a silicon carbide deburring disc designed for aggressive material removal on metal, plastic, and composite surfaces. At 2 inches in diameter with a 1/4 inch arbor center hole, this disc mounts directly to rotary tools and die grinders for fast deburring, edge blending, and surface prep work. Rated to a maximum of 12000 RPM, it handles high-speed applications without sacrificing control. The very coarse grade cuts quickly through burrs, flash, and rough edges left by machining, cutting, or stamping operations. Machinists, fabricators, and metalworkers reach for this disc when speed of material removal matters more than surface finish refinement.

This deburring disc suits bench-top and handheld rotary tool setups in fabrication shops, maintenance environments, and light manufacturing. The arbor mount makes it compatible with standard die grinders and rotary tools fitted with a 1/4 inch mandrel. Very coarse grade silicon carbide is well suited for initial deburring passes on ferrous and non-ferrous metals before finishing steps. The 2 inch diameter keeps the working footprint tight, making it practical for deburring drilled holes, slot edges, and confined part geometry where larger discs cannot reach.

Key Features

• Silicon carbide abrasive delivers fast, aggressive cutting on metals and composites
• Very coarse grade removes burrs, flash, and rough edges in fewer passes
• 2 inch diameter with 1/4 inch arbor hole fits standard die grinder mandrels
• 12000 RPM maximum speed rating supports high-speed rotary tool use
• Compact disc diameter allows access to tight part geometry and drilled hole edges

Compatibility

Designed for use with rotary tools and die grinders fitted with a 1/4 inch arbor mandrel. Suitable for deburring and edge-prep applications on metal, plastic, and composite workpieces.

Installation Notes

This disc is installed by a machinist or fabricator onto a 1/4 inch arbor mandrel mounted in a die grinder or rotary tool. Verify the tool's free-speed RPM does not exceed the 12000 RPM disc rating before operation. Always ensure the disc is fully seated and the arbor nut is tightened before running the tool. Wear appropriate eye protection and follow applicable shop safety procedures when operating abrasive discs at speed.
