3M 7010329113 Deburring Disc 12 in Fine Aluminum Oxide

Product Description

The 3M 7010329113 is an aluminum oxide deburring disc designed for light material removal, surface conditioning, and edge deburring on metal workpieces. Measuring 12 inches in diameter with a 1-1/4 inch center arbor hole, this disc mounts directly to compatible arbor-style backing pads on stationary or handheld disc grinders. The fine grade abrasive delivers controlled stock removal without aggressive surface damage, making it well suited for finishing passes and cleanup work after cutting or machining operations. Rated to a maximum of 1900 RPM, it is intended for use at appropriate machine speeds. The disc weighs 0.23 pounds.

This deburring disc is used in metal fabrication, manufacturing, and maintenance environments where burr removal and surface blending are required. It is appropriate for use on ferrous and non-ferrous metals in applications such as post-weld cleanup, edge conditioning, and light surface prep. Machinists, fabricators, and maintenance technicians are the primary installers. The arbor-mount design suits standard disc grinder setups found in production and job-shop environments alike.

Compatibility

Designed for use with arbor-style disc grinder backing pads that accept a 12 inch diameter disc with a 1-1/4 inch center hole. Verify machine RPM rating meets or does not exceed the 1900 RPM maximum before mounting.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive disc safety and applicable ANSI B11 or OSHA abrasive wheel standards. Power down and lock out the machine before mounting or removing the disc. Confirm the machine spindle speed does not exceed the disc maximum RPM rating of 1900. Inspect the disc for damage before each use and never operate a cracked or deformed abrasive disc.
