3M 7100175521 Deburring Disc 2 in Extra Coarse Silicon Carbide

Product Description

The 3M 7100175521 is a 2-inch diameter deburring disc designed to remove burrs, sharp edges, and surface irregularities from metal and other hard materials. It features a silicon carbide abrasive in an extra coarse grade, making it well suited for aggressive material removal in prep and finishing operations. A hook and loop connector system secures the disc to compatible backup pads for quick changes between passes. This disc is rated to a maximum of 18,000 RPM, supporting use on standard right-angle and die grinders found in fabrication shops, maintenance facilities, and mechanical service environments.

This deburring disc is used in light fabrication, metalworking, and industrial maintenance applications where fast edge cleanup and surface prep are required. It is appropriate for use on ferrous and non-ferrous metals, and fits common 2-inch hook and loop backup pads. The extra coarse silicon carbide abrasive cuts aggressively on harder surfaces where finer grades would load or glaze. Machinists, pipefitters, sheet metal workers, and maintenance technicians are the typical end users in both residential and commercial shop environments.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and unplugged or with the air supply disconnected on pneumatic tools. Confirm the backup pad and grinder are rated at or above the disc maximum RPM before mounting. Wear appropriate eye protection and gloves during disc changes and operation. Inspect the disc for damage before each use and discard any disc that shows tears, delamination, or irregular wear.
