3M 7010327687 Straight Cartridge Roll 120 Grit 5/16 in

Product Description

The 3M 7010327687 is a straight cartridge roll designed for precision grinding, deburring, and surface blending on metal and other hard materials. Built on a cloth backing with aluminum oxide abrasive, this roll delivers consistent fine-grade cutting action at up to 24,000 RPM. At 5/16 inches in diameter, it fits standard mandrels used in die grinders and rotary tools. Metal fabricators, maintenance machinists, and trade professionals use this type of roll for tight-radius internal work where flat abrasive tooling cannot reach. The 120-grit aluminum oxide construction suits finishing passes and light material removal where surface quality matters.

This cartridge roll is suited for use in metal finishing operations including weld cleanup, port blending, bore finishing, and deburring of drilled or punched holes. Its straight profile makes it appropriate for cylindrical or near-cylindrical workpiece features. Typical applications include aerospace component prep, fabrication shop finishing, and general industrial maintenance work. The cloth backing provides flexibility and durability under rotary load, making it a reliable choice for extended use in high-RPM handheld tooling.

Installation Notes

Installation of cartridge rolls should be performed by operators familiar with abrasive tooling and rotary power tools. Confirm the mandrel and tool spindle speed rating meet or exceed the 24,000 RPM maximum before use. Inspect the roll for damage before mounting and ensure the roll is fully seated and secured on the mandrel. Always use appropriate eye protection and follow applicable ANSI B11 or shop safety standards when operating high-speed abrasive tooling.
