3M 7000120513 Disc Pad Face Plate 4.5 Inches

Product Description

The 3M 7000120513 is a plastic disc pad face plate designed for use with 4.5-inch fibre discs in general purpose grinding applications. Constructed from plastic with medium flexibility, this face plate provides consistent backing support across the disc surface during grinding operations. It is compatible with a 2.5-inch disc pad hub and accepts fibre discs with a 0.875-inch center hole. Grinding technicians, fabricators, and metalworkers install this component as part of a complete angle grinder disc pad assembly to ensure proper disc seating and even pressure distribution during material removal tasks.

This face plate is suited for general purpose grinding applications in industrial, fabrication, and maintenance environments. It is intended for use with 4.5-inch fibre discs mounted on a 2.5-inch disc pad hub, making it a standard component in angle grinder setups used across metalworking, welding prep, and surface conditioning workflows. The medium-flexibility construction helps the disc conform slightly to workpiece contours while maintaining adequate rigidity for controlled stock removal.
