3M 7100080023 Straight Cartridge Roll 120 Grit 1/4 in

Product Description

The 3M 7100080023 is a straight cartridge roll designed for precision deburring, blending, and finishing on metal and other hard surfaces. Built with aluminum oxide abrasive on a cloth backing, it delivers consistent cut and durability under sustained use. At 0.25 inches in diameter and rated 120 grit, this roll falls in the fine grade range — well suited for controlled material removal and surface prep in tight bores, contoured channels, and internal radii. It is installed in die grinders and mandrel-mounted rotary tools and is commonly used by machinists, pipefitters, and fabrication shop technicians.

This cartridge roll is intended for use in rotary finishing applications where a small-diameter abrasive is required to access confined or internal workpiece geometry. Typical applications include cleaning weld seams inside tubing, blending surfaces in valve bodies, and deburring drilled or reamed holes in metal components. The fine 120-grit rating makes it appropriate for finish passes after coarser stock removal has been completed.

Key Features

• Aluminum oxide abrasive provides consistent cutting action on ferrous and non-ferrous metals
• Cloth backing adds flexibility and resistance to tearing during extended use
• 120 grit fine grade suitable for surface blending and finish work
• 0.25-inch diameter accesses tight bores and internal contours
• Rated up to 24000 RPM for use with standard die grinders

Compatibility

Designed for use with standard mandrel-mounted die grinders and rotary tools that accept straight cartridge rolls with a 0.25-inch diameter bore fitment.

Installation Notes

Installation is performed by sliding the cartridge roll onto a compatible mandrel and tightening per the mandrel manufacturer's guidance. Always ensure the tool is powered off and disconnected before mounting or removing abrasive accessories. Do not exceed the 24000 RPM maximum speed rating. Operators should follow applicable workplace safety standards and use appropriate eye and face protection when operating rotary abrasive tools.
