3M 7000120517 Disc Pad Face Plate Ribbed 5 in

Product Description

The 3M 7000120517 is a ribbed disc pad face plate designed for use with 5-inch diameter fibre discs in angle grinder and disc pad applications. The ribbed surface geometry creates intermittent contact zones that reduce heat buildup during grinding, which extends disc life when glazing or premature dulling is a problem. Rated extra hard and color-coded red, this face plate delivers higher localized pressure on the ribbed sections to maintain cutting action on harder materials. It is installed by grinding professionals and metalworking trades as a backing component in abrasive disc setups.

This face plate is intended for use in metal fabrication, weld blending, and surface preparation applications where heat management and disc longevity are priorities. The ribbed design is particularly effective in production environments where discs dull quickly under sustained pressure. It pairs with a 2.5-inch disc pad hub and accepts 5-inch diameter fibre discs, making it a standard-format component in portable grinding systems used across fabrication shops and field metalwork.

Key Features

• Ribbed face plate design reduces heat buildup for cooler disc operation
• Higher pressure on ribbed sections prolongs fibre disc life when dulling is a concern
• Extra hard durometer rating (red) for aggressive material removal applications
• Compatible with 5-inch diameter fibre discs and 2.5-inch disc pad hubs
• Lightweight construction at 0.15 pounds

Compatibility

Designed for use with 5-inch diameter x 7/8-inch fibre discs and a 2.5-inch disc pad hub as specified by the manufacturer.

Installation Notes

Installation is performed by grinding or fabrication technicians as part of a disc pad assembly. Power down and disconnect the grinder from its power source before mounting or removing the face plate. Ensure the face plate is fully seated and secured to the disc pad hub before operating the tool. Follow the tool manufacturer's guidelines and applicable ANSI abrasive safety standards during assembly and use.
