3M 45207 Face Plate Sanding Discs 5 Inch 9500 Rpm 5/8-11

Product Description

The 3M 45207 is a plastic face plate designed to back fibre and surface conditioning discs on angle grinders and disc sanders. It accepts a standard 5/8-11 threaded spindle and supports discs up to 5 inches in diameter with a 7/8 inch center hole. Rated to 9,500 RPM maximum, it provides a solid, stable mounting platform that keeps abrasive discs seated flat during grinding, blending, and surface conditioning work. Licensed tradespeople and skilled fabricators rely on this type of hardware to maintain consistent disc contact and reduce disc flutter on metal, fiberglass, and composite surfaces.

The 45207 face plate is suited for use in metal fabrication shops, maintenance environments, and general industrial applications where fibre discs or surface conditioning discs are regularly used. It is a direct-mount backing component that threads onto the spindle of a compatible right-angle grinder or disc sander. The 5 inch diameter and 5/8-11 thread make it a common fit for standard shop grinders used in both production and field settings.
