3M 7010327694 Straight Cartridge Roll 320 Grit 1/4 in

Product Description

The 3M 7010327694 is a straight cartridge roll designed for precision deburring, blending, and finishing in tight contours, slots, and internal diameters. Built on a cloth backing with 320-grit aluminum oxide abrasive, it delivers consistent very fine material removal on ferrous and non-ferrous metals. Rated to 24,000 RPM, it is compatible with standard mandrel-style rotary tools and die grinders. Machinists, fabricators, and metal finishing technicians use this roll where flat abrasive tooling cannot reach.

This cartridge roll is suited for bench-top and portable die grinder applications in precision metal fabrication, aerospace component finishing, and general shop work. It is commonly used to refine weld seams, smooth bores, and blend surface transitions in areas where larger abrasive tools lack access. The very fine 320-grit rating makes it appropriate for final finishing passes rather than aggressive stock removal.

Key Features

• 320-grit aluminum oxide abrasive for very fine finishing and surface blending
• Cloth backing provides flexibility and durability in contoured applications
• Straight cartridge roll geometry fits standard mandrel holders for die grinders
• Rated to 24,000 RPM for use with high-speed rotary tools

Compatibility

Designed as a standard straight cartridge roll for use with mandrel-style rotary tool holders and die grinders that accept 1/4-inch diameter cartridge rolls.

Installation Notes

A licensed or qualified machinist or metal finishing technician should mount the cartridge roll onto a compatible mandrel per the mandrel manufacturer's instructions. Ensure the tool is powered off and unplugged before mounting or removing the roll. Do not exceed the rated 24,000 RPM maximum speed. Inspect the roll for damage before each use and discard if the abrasive or backing shows signs of delamination or uneven wear.
