3M 7010328912 Deburring Disc 6 in Very Coarse Silicon Carbide

Product Description

The 3M 7010328912 is a 6-inch diameter deburring disc engineered for aggressive material removal on metal, plastic, and composite surfaces. Built with a silicon carbide abrasive in a very coarse grade, the disc cuts fast through burrs, scale, and surface irregularities left by machining, stamping, or casting operations. It mounts via a standard arbor connection and is rated to a maximum of 4,000 RPM. At 3.08 pounds, the disc is solidly constructed for consistent performance under sustained load. Metalworking professionals, fabricators, and maintenance technicians are the primary users of this product.

This disc is suited for bench grinder, angle grinder, or pedestal grinder applications where deburring and surface conditioning of ferrous and non-ferrous metals are required. It is a practical choice for production shops, job sites, and maintenance environments that need repeatable results on cut edges, drilled holes, and punched openings. The very coarse silicon carbide abrasive makes it especially effective on hard, brittle materials including cast iron and hardened steel.

Key Features

• 6-inch disc diameter for wide surface coverage per pass
• Silicon carbide abrasive delivers aggressive cutting action on hard materials
• Very coarse grade for rapid burr removal and edge conditioning
• Arbor mount connection for secure, centered installation on standard grinders
• 4,000 RPM maximum speed rating

Compatibility

Designed as an arbor-mount deburring disc compatible with standard 6-inch bench grinders and angle grinders that accept arbor-style disc attachments.

Installation Notes

Installation should be performed by a qualified metalworking technician or maintenance professional. Disconnect and lock out all power to the grinder before mounting or removing the disc. Confirm the grinder spindle speed does not exceed the 4,000 RPM maximum rating of the disc before operation. Inspect the disc for cracks or damage before each use and replace if any defects are found.
