3M 7010362433 Straight Cartridge Roll 180 Grit 5/16 in

Product Description

The 3M 7010362433 is a straight cartridge roll designed for precision grinding, deburring, and surface finishing in tight or contoured areas. Built on a cloth backing with aluminum oxide abrasive, this roll delivers consistent cut and finish at a very fine 180 grit. It measures 5/16 inches in diameter and is rated for a maximum of 24,000 RPM. Machinists, fabricators, and tool-and-die professionals use this type of cartridge roll when working inside bores, slots, or irregular profiles where flat abrasive media cannot reach.

This cartridge roll is suited for metalworking applications requiring fine surface preparation or blending on ferrous and non-ferrous metals. Typical use cases include deburring drilled holes, blending weld seams in confined spaces, and finishing internal radii on machined parts. The cloth backing provides flexibility to conform to curved surfaces while maintaining abrasive contact across the work area. It is sold individually but requires a minimum order quantity of 100 units.

Key Features

• Aluminum oxide abrasive for consistent cut on ferrous and non-ferrous metals
• Very fine 180 grit for finish grinding and surface blending
• Cloth backing provides flexibility for contoured and curved surfaces
• 5/16 inch diameter fits mandrels sized for small-bore and tight-access work
• Rated to 24,000 RPM for use with standard die grinders and rotary tools
• Straight profile allows uniform contact in cylindrical or slotted features

Compatibility

Designed for use with standard mandrel-style holders accepting 5/16 inch diameter straight cartridge rolls, as used with die grinders and rotary tools in metalworking and fabrication applications.

Installation Notes

Cartridge rolls are installed by a machinist or fabricator onto a compatible threaded or tapered mandrel fitted to a die grinder or rotary tool. Confirm the mandrel diameter matches the 5/16 inch roll bore before mounting, and verify the tool RPM does not exceed the 24,000 RPM rating of this roll. Always power down and disconnect the tool before changing abrasive media. Wear appropriate eye and hand protection during use.
