Standard Abrasives 7100074875 Non-woven Quick-change Disc

Product Description

The STANDARD ABRASIVES 7100074875 is a quick-change non-woven abrasive disc designed for surface conditioning, blending, and finishing on metal and other hard materials. Measuring 3 inches in diameter, it uses aluminum oxide abrasive material in a coarse grade, making it effective for aggressive stock removal and surface prep. The Type R attaching system allows fast, tool-free disc swaps on compatible right-angle die grinders and rotary tools. Rated at a maximum of 8000 RPM, this disc suits high-speed grinding applications in fabrication, maintenance, and repair environments. It is typically installed and operated by machinists, maintenance technicians, pipefitters, and general metalworkers.

This disc is suited for use in industrial, commercial, and trade shop environments where consistent surface preparation is required before welding, coating, or inspection. The non-woven construction conforms to irregular surfaces and contours, allowing even material removal without gouging the base material. The coarse grade is appropriate for removing rust, scale, weld spatter, and heavy oxidation from ferrous and non-ferrous metals. The green disc color provides quick visual identification in multi-disc setups.

Installation Notes

Installation is performed by securing the Type R disc onto a compatible mandrel attached to a die grinder or rotary tool. Verify the tool spindle speed does not exceed the 8000 RPM maximum rating of the disc before operation. Always wear appropriate eye protection and follow applicable ANSI B11 and workplace safety standards when operating abrasive products. Inspect the disc for damage before each use and do not use a disc that shows signs of deterioration.
