3M 7100102003 Straight Cartridge Roll 180 Grit 1/2 in

Product Description

The 3M 7100102003 is a straight cartridge roll abrasive designed for precision deburring, blending, and surface finishing on tight radiuses, slots, and contoured workpieces. Built on a cloth backing with aluminum oxide grain at 180 grit (Very Fine grade), it delivers consistent stock removal and smooth surface prep in hard-to-reach areas. Rated to a maximum of 24,000 RPM, this roll is suited for use on die grinders and mandrel-mounted rotary tools where control and finish quality matter. It is sold individually per package with a minimum order quantity of 100 units.

This cartridge roll is used in metal fabrication, aerospace component finishing, tool-and-die work, and general industrial grinding applications. It is well suited for working inside bores, ports, and contoured channels where flat abrasives cannot reach. The 0.5-inch diameter profile fits standard cartridge roll mandrels and is appropriate for both ferrous and non-ferrous metals including steel, aluminum, and cast iron. Machinists, fabricators, and maintenance technicians are the typical end users.

Compatibility

Designed for use with standard cartridge roll mandrels accepting 0.5-inch diameter straight cartridge rolls. Confirm mandrel shank size and RPM rating before installation.

Installation Notes

Install onto a compatible mandrel and confirm the roll is fully seated and the mandrel nut is secure before operation. Always verify the tool speed does not exceed the 24,000 RPM maximum rating of the roll. Wear appropriate PPE including eye protection and gloves when operating rotary abrasive tools. Inspect the roll for damage or separation before each use and discard if the backing shows signs of delamination.
