3M 7010363866 Straight Cartridge Roll 100 Grit 1/4 in

Product Description

The 3M 7010363866 is a straight cartridge roll designed for precision grinding, deburring, and finishing work in tight bores, tubes, and contoured surfaces. Built on a cloth backing with aluminum oxide abrasive, this roll delivers consistent cut rate and durability under extended use. At 1/4 inch diameter and 100 grit, it falls in the fine grade range, making it well-suited for controlled material removal and surface preparation before finishing. The roll is rated to a maximum of 24,000 RPM, compatible with standard pneumatic or electric die grinders used in metalworking and fabrication environments. Installation is straightforward on mandrel-style holders common in trade shops and field maintenance.

This cartridge roll is used primarily in metal fabrication, welding cleanup, pipe fitting, and general maintenance applications where access to a flat sanding surface is not practical. The 1/4 inch diameter targets small-diameter bores, weld joints, and edge work. It is appropriate for use on ferrous metals, aluminum, and similar hard surfaces. Trade professionals including machinists, pipefitters, welders, and maintenance technicians are the primary users. The fine 100 grit rating makes it effective for finishing passes where surface smoothness is a priority over aggressive stock removal.

Key Features

• Aluminum oxide abrasive on cloth backing for durability and consistent cut
• 100 grit fine grade for controlled surface finishing and light deburring
• 1/4 inch diameter for access to tight bores and confined weld areas
• Rated to 24,000 RPM for use with standard pneumatic die grinders
• Straight cartridge roll profile maintains uniform contact in cylindrical applications

Compatibility

Designed for use on standard mandrel-style arbors accepting 1/4 inch diameter straight cartridge rolls, as used with pneumatic and electric die grinders in metalworking and fabrication applications.

Installation Notes

Installation is performed by a machinist, fabricator, or maintenance technician using a compatible mandrel arbor fitted to a die grinder. Always confirm the tool spindle speed does not exceed the 24,000 RPM maximum rating of the roll before operation. Secure the mandrel per the tool manufacturer's instructions and inspect the cartridge roll for damage before each use. Disconnect or de-energize the tool before changing abrasive accessories.
