Standard Abrasives 7100074870 Quick-change Disc Tr 2in

Product Description

The STANDARD ABRASIVES 7100074870 is a 2-inch diameter non-woven quick-change disc designed for surface conditioning, blending, and light deburring on metal and similar substrates. Built with aluminum oxide abrasive in a medium grade, it delivers consistent cut and finish across a range of surface prep applications. The disc uses a TR (Type R) attaching system for fast, tool-free mounting on compatible right-angle grinders and disc holders. Rated to 12,000 RPM, it handles high-speed tool use without performance degradation. The non-woven construction conforms to irregular surfaces and resists loading, making it suitable for finishing passes where woven or coated abrasives would leave excessive scratch patterns.

This disc is used in metal fabrication, welding prep, and general maintenance grinding tasks common in industrial and commercial settings. The 2-inch diameter targets tight areas and smaller workpieces where a larger disc would be impractical. The TR quick-change system suits shops and field technicians who rotate through multiple abrasive types on a single tool. Typical installers include sheet metal workers, welders, pipefitters, and maintenance mechanics who need a fast-swap abrasive for blending welds, cleaning surfaces, or removing light oxidation.

Installation Notes
