3M 7000120518 Disc Pad Face Plate Ribbed 5 in

Product Description

The 3M 7000120518 is a ribbed disc pad face plate designed to back fibre discs during grinding and finishing operations. The ribbed surface geometry reduces heat buildup by allowing air movement across the disc face, keeping operating temperatures lower than a flat face plate. Higher contact pressure concentrates on the ribbed sections, which extends disc life in applications where rapid dulling is a concern. At 0.15 pounds, this hard black face plate is lightweight and straightforward to mount. It is installed by metalworking fabricators, welders, and maintenance technicians as part of an angle grinder or disc sander assembly.

This face plate is intended for use with 5 inch diameter fibre discs that have a 7/8 inch center hole, paired with a 2-1/2 inch disc pad hub. Typical applications include weld blending, surface preparation, rust removal, and material stock removal on metal workpieces. It suits both shop and field use wherever a 5 inch fibre disc setup is employed.

• Compatible with 5 inch diameter fibre discs with a 7/8 inch center hole
• Designed for use with a 2-1/2 inch disc pad hub
• Lightweight at 0.15 pounds for reduced operator fatigue

Compatibility

Designed for use with 5 inch diameter fibre discs with a 7/8 inch center hole and a 2-1/2 inch disc pad hub, as an OEM-style replacement or service component for compatible 3M disc pad assemblies.

Installation Notes

Installation is typically performed by a metalworking technician or maintenance professional. Power down and disconnect the grinder or sander from its power source before changing the face plate or disc. Ensure the hub and face plate are fully seated and secured before resuming operation. Follow the tool manufacturer's guidelines and applicable OSHA abrasive wheel safety requirements during assembly.
