3M 7010294686 Straight Cartridge Roll 40 Grit 1/4 in

Product Description

The 3M 7010294686 is a straight cartridge roll abrasive designed for deburring, blending, and finishing in tight spaces and contoured surfaces. Built with aluminum oxide grain on a cloth backing, this roll delivers coarse-grade cutting action at 40 grit. It measures 0.25 inches in diameter and is rated for a maximum spindle speed of 24,000 RPM. Machinists, fabricators, and grinding technicians use this type of cartridge roll with mandrel-mounted die grinders and pneumatic pencil grinders for internal bore work, slot finishing, and weld blending where larger abrasives cannot reach.

This cartridge roll fits applications in metal fabrication shops, aerospace component finishing, and general industrial grinding. The 0.25-inch diameter profile makes it well-suited for small-diameter holes, narrow channels, and confined weld joints. The cloth backing provides flexibility and durability under the pressure of rotary grinding operations. It is typically used in conjunction with a matching cartridge roll mandrel inserted into a die grinder or flexible-shaft tool.

Designed as an OEM-style replacement cartridge roll for use with standard 0.25-inch cartridge roll mandrels in die grinders and rotary tool setups used across general metalworking and fabrication applications.

Installation Notes

Installation requires a compatible cartridge roll mandrel sized for 0.25-inch rolls. Ensure the host tool is powered off and air supply is disconnected before mounting or removing the roll. Do not exceed the rated maximum speed of 24,000 RPM. Inspect the roll and mandrel for wear or damage before each use, and always wear appropriate eye and face protection during grinding operations.
