3M 7000045101 Quick-change Disc 100 Grit 1-1/2 Inches Roloc Tr

Product Description

The 3M 7000045101 is a Roloc TR quick-change abrasive disc designed for rapid disc swaps on Type R compatible grinders and die grinders. Built on a polyester cloth backing with a YF backing weight, this disc carries 100-grit aluminum oxide abrasive grain in a coated construction. At 1-1/2 inches in diameter, it is sized for tight-access grinding, blending, and surface prep work. The twist-and-lock Type R attachment system allows tool-free disc changes, reducing downtime during high-volume surface finishing tasks. Part of the 361F series, it is rated to 30,000 RPM, making it suitable for high-speed pneumatic and electric rotary tools.

This disc is used in metal fabrication, automotive bodywork, welding prep, and general industrial surface conditioning where a small-diameter disc is needed. The 1-1/2-inch size is well suited for weld blending in confined areas, deburring drilled holes, and cleaning up welds on tubing or sheet metal. The coated aluminum oxide grain provides consistent material removal on ferrous and non-ferrous metals. It is commonly used by welders, fabricators, and maintenance trades requiring fast disc changes in repetitive finishing operations.

Installation Notes

Installation and disc changes should be performed with the tool powered off and disconnected from the air supply or electrical source.
