3M 7100310728 Fiber Disc 36 Grit 5 Inches Tn Quick-change

Product Description

The 3M 7100310728 is a 5-inch ceramic fiber disc designed for aggressive material removal on metal, weld seams, and fabricated surfaces. It uses a Precision Shaped Ceramic abrasive grain bonded with a resinoid bond to a fiber backing, which extends disc life and maintains a consistent cut rate as the disc wears. The TN Quick-Change attachment system allows fast, tool-free disc swaps on compatible right-angle grinders. Rated to 12,000 RPM, this disc is sized for production metalworking and is part of the 3M 1182C Series. It is sold individually with a minimum order quantity of 25 units.

This disc is suited for use in fabrication shops, structural steel work, and heavy manufacturing environments where consistent stock removal and surface conditioning on ferrous metals are required. The 36-grit designation makes it appropriate for initial weld blending, deburring, and rough shaping operations. It is typically used by metal fabricators, welders, and industrial maintenance technicians working on carbon steel, stainless steel, and similar hard metals. The purple disc color identifies it as part of the Precision Shaped Ceramic line within the 1182C Series.
