Norton 78072709015 Quick-change Disc 3 in 80 Grit Ceramic

Product Description

The NORTON 78072709015 is a quick-change abrasive disc from the BlazeX F970 series, engineered for aggressive stock removal, weld blending, and deburring on metal surfaces. It features 100% ceramic alumina grain on a fiber backing rated for up to 20,000 RPM. The 3-inch diameter disc uses a Power-Lock Type R attaching system for fast, tool-free mounting on compatible handheld disc sanders. At 80 grit, it falls in the medium-to-coarse range, making it well-suited for rapid material removal without excessive loading. A self-lubricating grain treatment reduces heat buildup, and the resin bond system holds grain in place through the full disc life.

This disc is designed for use with handheld disc sanders in fabrication, maintenance, and metalworking applications. Typical use cases include weld blending, surface prep, deburring, and stock removal on ferrous and non-ferrous metals. Supported material applications listed by the manufacturer include 300 Series Stainless, 400 Series Stainless, Aluminum, Cast Iron, Gray Iron, Hard Carbon Steels, and Tool Steels. The flexible fiber backing conforms slightly to curved surfaces, extending its usefulness in contoured weld areas and irregular workpiece geometry. Individual discs are packaged and sold as single units.

Installation Notes

Installation is performed by metal fabricators and maintenance technicians using handheld disc sanders. Before mounting or removing a disc, ensure the sander is powered off and disconnected from its power source. Confirm the tool spindle speed does not exceed the 20,000 RPM maximum rating printed on the disc. Inspect the disc for cracks or damage before each use and replace immediately if defects are found.
