3M 7010363865 Straight Cartridge Roll 100 Grit 1/2 in

Product Description

The 3M 7010363865 is a straight cartridge roll designed for precision grinding, deburring, and surface blending on metal and other hard materials. Built with aluminum oxide abrasive on a cloth backing, it delivers consistent stock removal at a fine 100-grit rating. The roll spins at up to 24,000 RPM, making it well-suited for use with die grinders and rotary tools in tight spaces or contoured surfaces. Machinists, fabricators, and maintenance technicians install this type of abrasive roll for controlled finishing work where a flat abrasive cannot reach.

This cartridge roll is used in metalworking and fabrication environments for internal diameter finishing, weld blending, and deburring of bores, slots, and curved surfaces. It fits 1/2-inch diameter mandrels and is appropriate for both bench-mounted and handheld pneumatic or electric rotary tools. Typical applications include aerospace, automotive, and general metal fabrication shops where fine-grade surface finishing is required before inspection or coating.

Key Features

• Aluminum oxide abrasive provides durable, consistent cut on ferrous and non-ferrous metals
• Fine 100-grit rating suited for finish grinding and light deburring
• Cloth backing adds flexibility and resistance to tearing under load
• Straight cartridge roll geometry reaches bores, slots, and contoured surfaces
• Rated to 24,000 RPM for compatibility with high-speed rotary tools
• 1/2-inch diameter fits standard cartridge roll mandrels

Compatibility

Designed for use with standard straight cartridge roll mandrels accepting a 1/2-inch diameter roll, compatible with pneumatic and electric die grinders and rotary tools capable of operating at or below 24,000 RPM.

Installation Notes

Installation should be performed by a qualified machinist or fabricator familiar with rotary abrasive tooling. Before mounting, confirm the mandrel size matches the roll diameter and verify the tool's no-load RPM does not exceed the 24,000 RPM rating of the roll. Always use appropriate eye protection and hearing protection when operating abrasive tools, and inspect the roll for tears or damage before each use. Do not exceed the rated RPM under any circumstances.
