3M 7100101977 Straight Cartridge Roll 60 Grit 3/16 in

Product Description

The 3M 7100101977 is a straight cartridge roll designed for precision deburring, blending, and finishing work on metal, composite, and contoured surfaces. Built with aluminum oxide abrasive bonded to a cloth backing, this roll delivers consistent cut rates across its medium-grade 60-grit surface. The 3/16-inch diameter profile fits standard mandrel-driven rotary tools and die grinders, making it a practical choice for technicians working in tight bores, slots, and internal cavities. At a maximum speed rating of 24,000 RPM, it performs well under typical shop conditions. Sheet metal workers, pipefitters, welders, and maintenance techs are the primary users.

This cartridge roll is suited for light-to-moderate stock removal and surface prep on ferrous and non-ferrous metals in both shop and field applications. Its small diameter makes it particularly effective for internal diameter finishing, weld blending inside tubing, and deburring machined bores where larger abrasive tools cannot reach. It is sold individually per unit but carries a minimum order quantity of 100 pieces, making it appropriate for stocking in production shops or maintenance supply rooms.

Installation Notes

Installation is performed by qualified shop technicians or maintenance professionals using a compatible mandrel and rotary power tool.

Always wear appropriate eye protection and follow applicable shop safety procedures when operating rotary abrasives.
