3M 7000044902 Fiber Disc 3 in 60 Grit Ceramic Tr

Product Description

The 3M 7000044902 is a 3-inch ceramic fiber disc designed for aggressive material removal on metal and other hard surfaces. Part of the 982C series, it uses a ceramic abrasive grain bonded to a fiber backing with a resinoid bond system, delivering consistent cut and extended disc life compared to standard aluminum oxide alternatives. The TR Quick Change attachment type allows tool-free disc swaps at the grinder. Rated for a maximum of 20,000 RPM, this disc is built for use with compatible TR-style angle grinders in demanding fabrication and finishing environments.

This disc is appropriate for professional metalworking applications including weld blending, edge grinding, surface preparation, and stock removal on steel, stainless, and other ferrous substrates. At 60 grit medium grade, it cuts fast while leaving a surface profile suitable for subsequent finishing steps. It is sold individually but carries a minimum order quantity of 50 units, making it suited for shop stocking rather than single-job purchasing. Typical users include metal fabricators, pipefitters, and maintenance tradespeople who require reliable, repeatable cut performance across production workloads.

Installation Notes

Installation and disc changes should be performed by qualified personnel following the grinder manufacturer's instructions. Always ensure the tool is powered off and unplugged before mounting or removing the disc. Verify the grinder's rated RPM meets or exceeds the disc's 20,000 RPM maximum before use. Wear appropriate PPE including face shield and gloves during operation, in compliance with applicable ANSI and OSHA grinding safety standards.
