3M 7010327477 Straight Cartridge Roll 80 Grit 1/2 in

Product Description

The 3M 7010327477 is a straight cartridge roll designed for precision grinding, deburring, and surface blending on metal and other hard materials. Built with an aluminum oxide abrasive bonded to a cloth backing, this roll delivers consistent stock removal at an 80 grit, medium grade cut. It is rated for a maximum spindle speed of 24,000 RPM and is sized at 0.5 inches in diameter, making it well suited for tight bores, slots, and contoured surfaces that require controlled finishing passes. Machinists, fabricators, and tool-and-die technicians are the primary users of this consumable.

This cartridge roll is used in portable die grinders and stationary spindle machines for internal diameter grinding, weld blending, and deburring operations in manufacturing, fabrication, and maintenance environments. The 80 grit rating positions it as a general-purpose material removal tool where a medium surface finish is the target. It is appropriate for ferrous and non-ferrous metals in both production and repair applications.

Key Features

• Aluminum oxide abrasive for reliable stock removal on metal surfaces
• Cloth backing provides flexibility and durability under load
• 80 grit medium grade for balanced cut rate and surface finish
• 0.5 inch diameter fits standard die grinder mandrels and spindle tooling
• Rated to 24,000 RPM for compatibility with high-speed rotary tools

Compatibility

Designed as a standard straight cartridge roll for use with die grinders and spindle machines that accept 0.5 inch diameter cartridge roll mandrels.

Installation Notes

Installation is performed by threading the cartridge roll onto a compatible mandrel per the tooling manufacturer's instructions. Always verify that the grinder or spindle machine does not exceed the 24,000 RPM maximum speed rating before operating. Wear appropriate eye and face protection when using rotary abrasives. Inspect the roll for damage or looseness before each use and replace if any deterioration is visible.
