3M 7100272237 Quick-change Disc 2 in Ceramic Non-woven

Product Description

The 3M 7100272237 is a Roloc TR quick-change abrasive disc designed for surface conditioning, blending, and finishing applications in metal fabrication, welding prep, and industrial maintenance work. Built with a ceramic non-woven abrasive construction in a Very Fine grade, this disc delivers consistent material removal with a controlled cut. The Type R attaching system allows fast one-motion disc changes on compatible quick-change tools, reducing downtime during repeated passes. Rated to 25000 RPM maximum, it is suited for high-speed angle grinders and die grinders used by fabricators, pipefitters, and maintenance technicians.

This disc is intended for light deburring, surface blending, and finishing on ferrous and non-ferrous metals, plastics, and composites. The non-woven ceramic construction conforms to contours and workpiece surfaces, making it well-suited for weld blending and pre-paint surface prep on sheet metal, structural steel, and tubing. It is sold individually and fits tools with Type R or TR quick-change arbors commonly used in professional fab shops and field maintenance environments.
