3M 7010327686 Straight Cartridge Roll 120 Grit 3/4 in

Product Description

The 3M 7010327686 is a straight cartridge roll abrasive designed for use with rotary die grinders and mandrel-style tooling. It features a 120-grit aluminum oxide abrasive on a cloth backing, placing it in the fine grade range. The 0.75-inch diameter profile fits standard cartridge roll mandrels and is suited for deburring, blending, and light material removal on metal surfaces. Machinists, fabricators, and maintenance technicians working on tight contours, bores, and inside radii rely on this style of abrasive. The cloth backing provides flexibility and durability under consistent rotational load at speeds up to 16,000 RPM.

This cartridge roll is used in metal fabrication, tool and die, maintenance and repair, and general industrial finishing applications. It is well suited for working inside drilled holes, slots, and curved surfaces where flat abrasive media cannot reach. The fine 120-grit cut makes it appropriate for finishing passes and surface blending rather than aggressive stock removal. It is sold individually per piece, with a minimum order quantity of 100 units.

Installation Notes

Install onto a compatible mandrel and tighten per the mandrel manufacturer's instructions before use. Confirm the die grinder's free speed does not exceed the 16,000 RPM rating of the cartridge roll. Inspect the roll for damage before each use and do not use rolls that show fraying, separation, or deformation. Always wear appropriate eye protection and follow applicable shop safety procedures when operating rotary abrasive tools.
