3M 7000120521 Disc Pad Face Plate 5 Inches

Product Description

The 3M 7000120521 is a disc pad face plate designed for use with 5-inch fibre discs in blending and light-duty grinding applications. Constructed from a soft engineered resin, the face plate provides controlled backing that helps the fibre disc conform to workpiece contours during use. It is compatible with a 2.5-inch disc pad hub and accepts fibre discs with a 7/8-inch center hole. This type of accessory is typically installed by metalworkers, fabricators, and finishing technicians who require consistent disc support and even pressure distribution across the abrasive surface.

This face plate is suited for light-duty grinding and blending tasks on metal surfaces in fabrication shops, maintenance facilities, and similar industrial environments. It pairs with standard 5-inch fibre discs to support stock removal, weld blending, and surface preparation work. The soft resin construction makes it appropriate for applications where a degree of flex is needed rather than rigid backing.

Key Features

• Soft engineered resin construction allows controlled flex during blending and grinding
• Fits 5-inch fibre discs with a 7/8-inch center hole
• Compatible with 2.5-inch disc pad hub

Compatibility

Designed for use with 5-inch x 7/8-inch center hole fibre discs and a 2.5-inch disc pad hub for blending and light-duty grinding applications.

Installation Notes

Installation is typically performed by grinding and finishing technicians. Before mounting or removing the face plate, ensure the grinder is fully powered off and unplugged or locked out per applicable safety procedures. Verify the hub size and disc center hole dimensions match before assembly. Do not exceed the maximum RPM rating of the fibre disc being used with this face plate.
