3M 7000045285 Disc Backing Pad Quick-change Type R

Product Description

The 3M 7000045285 is a 3-inch disc backing pad designed for use with Quick-Change Type R abrasive discs in pneumatic and electric angle grinder applications. Built with an extra-hard density construction, it provides firm, consistent support across the disc surface for aggressive stock removal and finishing work. The pad accepts a 1/4-20 female thread mount and is rated to a maximum of 20,000 RPM, making it suitable for high-speed grinding, blending, and surface preparation tasks. Metal fabricators, maintenance technicians, and industrial tradespeople rely on this pad for consistent disc contact and repeatable results across a range of surface work.

This backing pad is intended for use in industrial and manufacturing environments where Quick-Change Type R compatible discs are the standard. It is well-suited for applications including weld blending, edge deburring, paint removal, and surface conditioning on metal substrates. The Roloc TR quick-change system allows for fast disc swaps without tools, reducing downtime during production or repair operations. It fits standard die grinders and angle grinders equipped with a 1/4-20 threaded spindle.
