3M 7100032359 Cubitron Ii 967A Flap Disc 60 Grit 4.5 in T29

Product Description

The 3M 7100032359 is the Cubitron II 967A flap disc, a Type 29 right-angle abrasive disc engineered for medium-pressure grinding and surface preparation. Built with 3M Precision-Shaped Grain, it delivers a fast, consistent cut rate across its full service life. The 4.5-inch diameter disc runs at 60 grit, making it well suited for weld leveling, light deburring, and surface prep before paint. A poly-cotton backing promotes controlled, even wear under medium unit pressure, reducing the risk of gouging compared to fiber discs and bonded wheels.

This disc is designed for use on mild steel and stainless steel. Common applications include weld removal, seam blending, and surface preparation in fabrication and metalworking environments. Its contoured Type 29 profile allows effective work on both flat and curved surfaces. The disc is appropriate for light industrial and job-site use where finish quality and gouge resistance matter, particularly in stainless steel work where surface integrity is a priority.

Installation Notes

This disc is installed and serviced by metalworking and fabrication professionals. Before mounting, confirm the grinder spindle speed rating meets or exceeds the disc maximum RPM rating. Power down and disconnect the grinder before changing discs. Inspect the disc for damage before each use and do not use a disc that is cracked, frayed, or delaminated.
