3M 7000120460 Roloc Disc Pad Assembly 1 Inch

Product Description

The 3M 7000120460 is a backup pad assembly designed to support Roloc 1 inch diameter abrasive discs in rotary tool applications. The pad features a 1/4-20 INT threaded mount, allowing direct attachment to tools equipped with a 1/4-20 EXT threaded shaft. The assembly includes a Roloc shank and adaptor, making it a complete, ready-to-install unit. Commonly installed by metalworkers, auto body technicians, fabricators, and maintenance professionals, this pad provides consistent backing support during surface prep, grinding, and finishing operations. Weighing 0.23 pounds, the lightweight construction minimizes user fatigue during extended use.

This disc pad assembly is suited for applications where 1 inch Roloc abrasive discs are used on die grinders, drill motors, or other rotary tools with compatible threaded shafts. Typical use cases include weld cleanup, surface conditioning, deburring, and blending on metal, fiberglass, and similar substrates. The integrated shank and adaptor eliminate the need for separate mounting hardware, streamlining tool changeovers in production and repair environments.
