Walter Surface Technologies 07R452 Deburring Disc 4-1/2 in

Product Description

The WALTER SURFACE TECHNOLOGIES 07R452 is a flexible aluminum oxide deburring disc designed for surface blending, deburring, and light material removal on metal workpieces. Part of the QS Blendex series, it measures 4-1/2 inches in diameter with a 7/16-inch center hole and attaches via a hook and loop backing for quick disc changes. Rated to 11,000 RPM, this coarse-grade disc is suited for use with right-angle grinders and random orbital tools. It is installed and used by metalworkers, fabricators, pipefitters, and maintenance technicians who require consistent surface finishing performance on steel, stainless, and aluminum.

The 07R452 is intended for deburring, blending, and surface preparation applications on flat or contoured metal surfaces. Its flexible construction allows it to conform to irregular workpiece profiles, making it practical for weld blending, edge breaking, and rust or scale removal. The coarse grade provides aggressive material removal suitable for initial pass work before finer finishing steps. This disc fits standard 4-1/2-inch angle grinder backings equipped with a compatible hook and loop interface.

Installation Notes

This disc is installed and replaced by metalworkers, fabricators, and maintenance technicians using standard 4-1/2-inch grinder equipment. Before mounting or removing the disc, ensure the grinder is powered off and disconnected from its power source. Verify that the tool RPM rating meets or exceeds the disc maximum rating of 11,000 RPM before operation. Always wear appropriate eye, face, and hand protection when operating abrasive discs.
