Superior Abrasives A008325 Deburring Disc 4.5 in Very Coarse

Product Description

The SUPERIOR ABRASIVES A008325 is a silicon carbide deburring disc designed for material removal and surface preparation on metal workpieces. Measuring 4-1/2 inches in diameter with a 7/8-inch center arbor hole, this disc mounts directly to a variable speed angle grinder and delivers aggressive cutting action at up to 11,000 RPM. The very coarse grade is suited for fast deburring, edge cleaning, and scale removal on ferrous and non-ferrous metals. Trade professionals in HVAC fabrication, plumbing rough-in, and general metalwork use this disc for rapid stock removal where finish quality is secondary to speed.

This deburring disc fits standard variable speed angle grinders equipped with a 7/8-inch arbor. It is appropriate for shop and field use in light industrial, commercial, and residential trade environments. Typical applications include cleaning weld seams, removing sharp burrs from cut pipe or sheet metal, and preparing mating surfaces before assembly. The silicon carbide abrasive cuts efficiently on cast iron, non-ferrous metals, and masonry surfaces where aluminum oxide would wear prematurely.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with angle grinder safety procedures. Always power down and unplug the grinder before mounting or removing any disc. Confirm the grinder's no-load RPM rating does not exceed the disc's 11,000 RPM maximum before operation. Wear appropriate PPE including a face shield and gloves, and inspect the disc for cracks or damage before each use.
