3M 7000045620 Quick-change Disc 60 Grit 1 Inch Ceramic

Product Description

The 3M 7000045620 is a ceramic-abrasive quick-change disc designed for use with Roloc TR and Type R disc holders. It features a 1-inch diameter, 60-grit ceramic abrasive on a polyester cloth backing, and is rated for a maximum speed of 30,000 RPM. The orange-faced, YF-weight backing delivers consistent cut and durability under moderate-to-aggressive grinding conditions. This disc is part of the 3M 777F series, engineered for coated-abrasive applications where fast stock removal and long disc life are priorities. HVAC fabricators, sheet metal workers, plumbers, and general trade mechanics use these discs for deburring, blending, and material removal on metal surfaces.

This disc is suited for light to medium material removal on metal, stainless steel, and similar hard surfaces. The quick-change Type R attachment system allows fast disc swaps without tools, making it practical in production environments and field service where downtime between abrasive changes needs to stay minimal. The 1-inch diameter is appropriate for tight spaces, pipe ends, fittings, and small-surface weld preparation work common in trade installations.
