3M 7000119103 Wave Washer Disc Sander Die Grinder Part

Product Description

The 3M 7000119103 is a replacement wave washer designed for use in 3M power tools including disc sanders, die grinders, and cut-off wheel tools. Wave washers provide controlled axial load and absorb vibration between rotating or stationary components, helping maintain consistent tension and reducing wear within tool assemblies. This washer measures 0.440 inches inner diameter, 0.618 inches outer diameter, and 0.008 inches in thickness. It is sold individually and is intended for use by technicians performing scheduled maintenance or component-level repairs on 3M pneumatic and electric tool platforms.

This wave washer is suited to repair or maintenance scenarios where worn, fatigued, or damaged washers within a tool assembly need replacement. Disc sanders, die grinders, and cut-off tools used in fabrication, bodywork, metalworking, and finishing applications put repetitive stress on internal components. Replacing worn wave washers restores proper spring tension and helps return the tool to factory operating specifications. Always reference the applicable tool owner manual and parts list schematic to confirm correct placement and quantity before installation.
