3M 7000144144 Disc Pad Face Plate 4.5 in Hard Black

Product Description

The 3M 7000144144 is a hard black disc pad face plate designed for use with 4.5-inch fibre discs in general purpose grinding applications. Molded from a hard engineered resin, this face plate provides a rigid backing surface that supports consistent disc contact and even material removal during grinding. It is compatible with a 2.5-inch disc pad hub and accepts fibre discs with a 0.875-inch center hole. Licensed tradespeople in metal fabrication, construction, and maintenance trades rely on this type of face plate to maintain proper disc alignment and backing support throughout a grinding operation.

This face plate is suited for use on angle grinders fitted with a 4.5-inch fibre disc setup. It is intended for general purpose grinding tasks on metal and similar materials in both shop and field environments. The hard plastic construction keeps the disc flat against the work surface, which is critical for consistent stock removal and disc longevity. It is sold individually and designed to pair with a 2.5-inch disc pad hub assembly.
