Walter Surface Technologies 07R453 Deburring Disc 4.5in

Product Description

The WALTER SURFACE TECHNOLOGIES 07R453 is an aluminum oxide deburring disc designed for surface conditioning, deburring, and blending operations on metal workpieces. Part of the QS Blendex series, this flexible disc mounts via a hook and loop connector for fast changeovers on compatible backing pads. At 4-1/2 inches in diameter with a 7/16 inch center hole, it fits standard right-angle grinders and disc sanders commonly used in fabrication and metalworking. Medium grade aluminum oxide provides effective material removal and edge cleanup without aggressive stock removal, making it well suited for finishing passes and light deburring tasks.

This disc is intended for trade professionals in metal fabrication, welding, pipefitting, and maintenance work where consistent surface finish and edge preparation are required. The flexible construction allows the disc to conform to contoured or irregular surfaces, improving contact and finish uniformity. Typical applications include weld spatter removal, burr cleanup on cut edges, and pre-inspection surface blending on structural steel, pipe, and sheet metal components.

Installation Notes

Installation is performed by metalworkers, fabricators, and maintenance technicians using standard right-angle grinders equipped with a compatible hook and loop backing pad. Before mounting or removing the disc, ensure the grinder is unplugged or the battery is removed and the disc has come to a complete stop. Never exceed the 11,000 RPM maximum speed rating marked on the disc. Inspect the disc for tears, delamination, or abrasive loss before each use and discard any disc showing visible damage.
