3M 7000121874 Surface Conditioning Gp Disc 5 Inch Coarse

Product Description

The 3M 7000121874 is a Surface Conditioning GP abrasive disc designed for deburring, blending, and cleaning on aluminum and other soft metals. Built on a flexible GP substrate with an Aluminum Oxide mineral, it delivers high initial cut rate and extended material removal across the disc life. The 5-inch diameter and 0.87-inch arbor configuration make it a direct fit for standard right-angle grinders and disc sanders used in metal fabrication and finishing operations. Licensed tradespeople in sheet metal, HVAC fabrication, and light manufacturing rely on this disc for both flat and contoured surface work.

This disc is suited for residential and commercial metalworking applications where low contact pressure is required and load resistance is a priority. It performs on ferrous materials as well as aluminum and other non-ferrous soft metals. Typical use cases include blending welds, removing coatings, light deburring of edges, and surface finishing on both flat panels and curved profiles. The Hook and Loop attachment system allows fast disc changes without additional hardware, making it practical for high-turnover production environments.

Installation Notes

Disc installation and replacement should be performed by trained metalworking or sheet metal professionals. Power down and disconnect the tool from its power source before mounting or removing the disc. Confirm the arbor size and spindle thread match your tool specifications before attaching. Always verify the tool RPM rating does not exceed the disc RPM rating prior to use.
