3M 45193 Abrasive Disc Face Plate 7 in 5/8-11 7000 Rpm

Product Description

The 3M 45193 is a plastic face plate designed to back and secure abrasive discs during grinding and surface preparation work. It accepts discs up to 7 inches in diameter and mounts via a 5/8-11 threaded arbor, the standard spindle thread found on most angle grinders and right-angle disc grinders. The 45193 is rated to 7,000 RPM, keeping it within the operating envelope of common grinder platforms used in metal fabrication, weld blending, and surface conditioning. Installation is straightforward and is typically performed by metalworkers, fabricators, and maintenance technicians who change abrasive discs regularly.

This face plate suits applications where a rigid plastic backing is preferred over a rubber or fiber backing pad. It is appropriate for use with resin-fiber discs and similar flat abrasive disc formats in both shop and field environments. The 5/8-11 thread mount makes it a direct fit for standard angle grinders used across industrial, commercial, and heavy maintenance settings. It is sold as a single unit.

Installation Notes

Installation and disc changes should be performed by qualified operators following the grinder manufacturer's instructions and applicable ANSI B11 or OSHA abrasive wheel safety guidelines. Always power down and disconnect the grinder from its power source before mounting or removing the face plate. Confirm the maximum RPM rating of the face plate meets or exceeds the no-load speed of the grinder before use. Do not exceed the rated disc diameter or RPM.
