Merit Abrasives 66261194392 Cartridge Roll 3/8 in 60 Grit

Product Description

The MERIT ABRASIVES 66261194392 is a straight cartridge roll designed for precision grinding, deburring, and surface finishing in tight or contoured areas. Built with a ceramic abrasive grain on a cloth backing, this roll delivers consistent stock removal at a medium grade. The 3/8 inch diameter profile fits standard mandrels used in die grinders and portable drilling tools. With a maximum operating speed of 18,000 RPM, it handles the pace of production work as well as detail finishing tasks. Machinists, fabricators, and maintenance technicians are the primary users in shop and field environments.

This cartridge roll is suited for use on metals including steel, stainless steel, and cast iron, where a consistent scratch pattern and controlled material removal are required. It performs well in internal bores, weld seams, slots, and curved surfaces that flat abrasives cannot reach. The cloth backing provides flexibility and conformability, making it a practical choice for contoured workpiece geometry in both job-shop fabrication and maintenance repair operations.
