3M 7010309043 Aluminum Oxide Cartridge Roll 80 Grit

Product Description

The 3M 7010309043 is an aluminum oxide cartridge roll designed for precision grinding, deburring, and surface blending in metal fabrication and finishing applications. Built on an X-weight cloth backing with resin bonding, it delivers consistent cut rate and heat resistance through demanding abrasive cycles. The roll measures 0.75 inches in diameter by 1.5 inches in length with a 0.125-inch arbor hole, and runs at 80 grit for moderate-to-aggressive stock removal. Machinists, fabricators, and finishing technicians use this roll where a mounted abrasive is required in a die grinder or rotary tool setup.

This cartridge roll is suited for internal diameter grinding, port matching, weld blending, and edge deburring on ferrous and non-ferrous metals. The X-weight cloth backing resists tearing under lateral pressure, making it appropriate for contoured surfaces and tight bores where flat abrasives cannot reach. It is sold in minimum quantities of 100 rolls per order, consistent with production-volume shop use.

Key Features

• Aluminum oxide abrasive mineral for reliable cut on steel, cast iron, and aluminum
• X-weight cloth backing provides durability and resistance to tearing under load
• Resin bond construction enhances heat resistance during extended grinding cycles
• 80 grit for moderate stock removal and surface blending
• Compact 0.75 inches x 1.5 inches x 0.125 inches form factor fits standard cartridge roll mandrels

Compatibility

Designed for use with standard cartridge roll mandrels in die grinders and rotary tools that accept a 0.125-inch arbor shaft. Verify mandrel compatibility and maximum RPM rating before mounting.

Installation Notes

Installation is performed by fabricators or machinists using a compatible cartridge roll mandrel. Ensure the grinder is powered off and disconnected from the air or electrical supply before mounting or removing the roll. Do not exceed the maximum RPM rating marked on the roll or mandrel. Inspect the roll for damage before each use and replace if tearing, separation, or uneven wear is observed.
