3M 7100080022 Straight Cartridge Roll 60 Grit 1/4 in

Product Description

The 3M 7100080022 is a straight cartridge roll abrasive designed for precision grinding, deburring, and surface blending in tight spaces and contoured areas. Built on a cloth backing with aluminum oxide abrasive grain at 60 grit (medium grade), this roll delivers consistent material removal on ferrous and non-ferrous metals. It mounts on a mandrel and spins at up to 24,000 RPM, making it well suited for die grinders and high-speed rotary tools. The 0.25-inch diameter profile allows access to slots, holes, and recessed surfaces that larger abrasives cannot reach. Machinists, fabricators, and tool-and-die technicians reach for this style of roll when finishing interior bores or chamfering edges by hand tool.

This cartridge roll is used in metalworking, fabrication, and maintenance applications where controlled stock removal is needed in confined geometries. Typical uses include weld blending inside pipe joints, deburring drilled holes, and cleaning up casting flash in recessed areas. The medium grit rating makes it appropriate for initial material removal before stepping up to finer abrasives. It is sold individually (package quantity of 1) and is available in multiples of 100 units for shop or production environments.

Key Features

• Aluminum oxide abrasive grain for consistent cutting on steel, cast iron, and non-ferrous metals

• Cloth backing provides durability and flexibility in contoured or recessed areas
• 0.25-inch diameter fits standard mandrels used with die grinders and rotary tools
• Rated to 24,000 RPM maximum for compatibility with high-speed rotary equipment
• Straight cartridge form for consistent, predictable wear during use

Compatibility

Designed for use with standard mandrels and die grinders that accept 0.25-inch diameter straight cartridge rolls rated for up to 24,000 RPM operation.

Installation Notes

Installation is performed by a machinist or fabricator using a compatible mandrel and rotary tool. Confirm the tool spindle speed does not exceed the 24,000 RPM maximum rating marked on the roll before use. Secure the mandrel firmly and inspect the cartridge roll for tears or loose abrasive before powering the tool. Always wear appropriate eye and face protection when operating rotary abrasive equipment.
