3M 7010362429 Straight Cartridge Roll 150 Grit 3/16 in

Product Description

The 3M 7010362429 is a straight cartridge roll abrasive designed for precision material removal and finishing in tight contours, slots, and bore surfaces. Built with an aluminum oxide abrasive bonded to a cloth backing, it runs at up to 24,000 RPM and delivers a very fine 150-grit cut. The 3/16-inch diameter makes it well-suited for narrow internal surfaces where larger tooling cannot reach. Machinists, metal fabricators, and tool-and-die technicians typically use this cartridge roll with mandrel-mounted die grinders or rotary tools for deburring, blending, and surface preparation work.

This cartridge roll fits common light-to-medium finishing applications on metals, including ferrous and non-ferrous stock. The cloth backing provides flexibility and durability when working inside contoured channels, drilled holes, and machined recesses. At 150 grit, it is appropriate for final deburring passes and pre-finishing work where surface consistency is required before inspection or coating. It is sold individually and requires a compatible straight-mandrel holder sized for 3/16-inch diameter rolls.

Key Features

• Aluminum oxide abrasive grain for consistent cut on ferrous and non-ferrous metals
• Cloth backing provides flexibility and tear resistance in contoured applications
• 150-grit very fine grade for deburring and pre-finish surface blending
• 3/16-inch diameter for access to narrow bores, slots, and recesses
• Rated to 24,000 RPM for compatibility with standard die grinders and rotary tools

Compatibility

Designed for use with straight mandrel holders that accept 3/16-inch diameter cartridge rolls; confirm mandrel compatibility before use.

Installation Notes

Installation is performed by machinists or fabricators using a rotary die grinder or similar power tool. Secure the mandrel per the tool manufacturer's torque recommendation and confirm the roll is seated fully before operation. Do not exceed the rated 24,000 RPM maximum speed. Always wear appropriate eye protection and ensure the workpiece is secured before beginning any grinding or finishing pass.
