3M 7010363862 Straight Cartridge Roll 80 Grit 5/16 in

Product Description

The 3M 7010363862 is a straight cartridge roll abrasive designed for precision grinding, deburring, and blending in tight or contoured areas. Built with an aluminum oxide abrasive bonded to a cloth backing, it delivers consistent material removal at an 80 grit (medium grade) cut rate. The straight profile fits standard mandrel-mounted setups used in die grinders and flexible shaft machines. With a maximum operating speed of 24,000 RPM, it suits high-speed rotary tools common in metalworking and fabrication environments. Machinists, tool-and-die technicians, and fabricators typically use this roll for finishing internal bores, slots, and irregular contours where flat abrasives cannot reach.

This cartridge roll is suited for use in metal fabrication shops, maintenance and repair operations, and light industrial production environments. Its 5/16 inch diameter makes it a go-to choice for accessing narrow cavities, small bores, and recessed weld joints. It is compatible with standard cartridge roll mandrels and is typically used in die grinders or flexible shaft tools running at appropriate RPM ranges. Common applications include deburring castings, blending weld seams, and surface conditioning on steel, aluminum, and similar metals.

Key Features

• Aluminum oxide abrasive for consistent cut on ferrous and non-ferrous metals
• 80 grit medium grade for material removal and surface blending
• Cloth backing provides durability and flexibility in contoured applications
• 5/16 inch diameter fits narrow bores and restricted access areas
• Rated to 24,000 RPM for use with high-speed rotary and die grinder tools
• Straight cartridge profile mounts on standard mandrel tooling

Compatibility

Designed for use with standard cartridge roll mandrels in die grinders and flexible shaft machines. Verify mandrel diameter matches the 5/16 inch roll bore before installation.

Installation Notes

Installation is typically performed by machinists or fabricators using a compatible mandrel and a die grinder or flexible shaft tool. Ensure the tool is disconnected from power before mounting or removing the cartridge roll. Never exceed the rated maximum speed of 24,000 RPM, as overspeeding an abrasive roll creates a risk of breakup and injury. Inspect the roll for damage before each use and discard if the abrasive or backing shows signs of delamination or unraveling.
