3M 7010363847 Straight Cartridge Roll 50 Grit 1/2 in

Product Description

The 3M 7010363847 is a straight cartridge roll abrasive designed for precision material removal in tight spaces and contoured surfaces. Built with aluminum oxide grain on a cloth backing, it delivers consistent coarse-grade cutting action at up to 24,000 RPM. At 0.5 inches in diameter, this cartridge roll fits standard mandrel-mounted rotary tools used in metalworking, weld blending, and deburring operations. Machinists, fabricators, and maintenance technicians reach for this type of abrasive when working inside bores, slots, or curved profiles where flat abrasive sheets cannot reach.

This cartridge roll is suited for aggressive stock removal on ferrous and non-ferrous metals, as well as hardwood and composite materials. The 50-grit coarse grade makes it appropriate for initial shaping, weld seam blending, and surface conditioning before stepping down to finer grits. It is commonly used in production grinding, toolroom work, and field repair environments where a mandrel-mounted rotary tool or die grinder is the primary equipment.

Key Features

• Coarse grade 50 grit suited for aggressive stock removal and initial surface shaping
• Cloth backing offers flexibility and tear resistance under high-speed rotation
• 0.5 inch diameter fits standard mandrel sizes used with die grinders and rotary tools
• Rated to 24,000 RPM for compatibility with high-speed pneumatic and electric rotary tools

Compatibility

Designed as an OEM-style mandrel-mounted cartridge roll for use with standard die grinders and rotary tools that accept 0.5 inch diameter straight cartridge roll abrasives.

Installation Notes

Installation is performed by trade machinists, fabricators, or maintenance technicians using a compatible mandrel and rotary tool. Before mounting, confirm the tool's rated RPM meets or exceeds the 24,000 RPM rating of this cartridge roll. Secure the mandrel and roll assembly per the tool manufacturer's instructions and ensure the workpiece is stable before beginning operation. Always wear appropriate eye and hand protection when operating rotary abrasives.
