3M 7000120462 Fibre Disc Backup Pad 5x7/8 in 10pk

Product Description

The 3M 7000120462 is a fibre disc backup pad designed to support and drive abrasive fibre discs during grinding and finishing operations. It mounts to angle grinders and similar rotary tools via a 7/8-inch arbor and provides a rigid, consistent backing surface across the full 5-inch disc diameter. This backup pad helps maintain even contact pressure between the disc and the workpiece, which extends disc life and improves surface consistency. It is sold in a case quantity of 10 pads and is a standard consumable tool accessory used by fabricators, welders, pipefitters, and other trade professionals who regularly run fibre discs.

This backup pad is suited for use in metal fabrication shops, mechanical rooms, and field service environments where angle grinders are used for weld blending, rust removal, and surface preparation. The 5-inch diameter and 7/8-inch arbor bore are among the most common configurations in commercial and industrial grinding applications. Installers in plumbing, HVAC, and general mechanical trades who work with pipe and sheet metal will find this pad compatible with standard fibre disc workflows.
