3M 7010309040 Cartridge Roll P120 Grit X-weight Cloth

Product Description

The 3M 7010309040 is a ceramic grain abrasive cartridge roll built on an X-weight cloth backing and resin-bonded for elevated heat resistance. It measures 0.5 inches in diameter by 1.5 inches in length with a 0.125-inch arbor hole and carries a P120 grit designation. The ceramic grain construction includes a grinding aid that helps reduce heat buildup at the contact zone, extending cut life and reducing workpiece discoloration. This cartridge roll is designed for use in high-speed rotary tools and die grinders operated by machinists, fabricators, and metalworking professionals who require consistent stock removal in tight or contoured areas.

This roll is suited for deburring, blending, and surface conditioning on ferrous and non-ferrous metals, as well as hard alloys where consistent finish and cut rate matter. Its compact 0.5-inch by 1.5-inch profile makes it effective inside bores, slots, ports, and other confined geometries where flat abrasives cannot reach. P120 grit positions it for intermediate material removal and pre-finishing work before finer abrasive steps. Sold in rolls, minimum order quantity is 100 units per the supplier specification.

Key Features

• Ceramic abrasive grain for aggressive, consistent cut rate on hard metals
• X-weight cloth backing provides durability under high-contact-pressure applications
• Resin bond system rated for heat resistance during extended grinding cycles
• Integrated grinding aid promotes cooler grinding and reduces heat-induced workpiece damage
• P120 grit suited for intermediate stock removal and surface blending
• Compact 0.5 inches x 1.5 inches profile fits bores, ports, and contoured surfaces

Compatibility

Designed as an OEM-style replacement-grade abrasive cartridge roll for use with standard mandrel-driven rotary die grinders and high-speed rotary tools accepting a 0.125-inch arbor.

Installation Notes

Installation is performed by machinists, tool-and-die technicians, and metal fabricators using standard cartridge roll mandrels matched to the 0.125-inch arbor size. Confirm the mandrel and tool RPM rating meets or exceeds the abrasive roll rating before mounting. Secure the roll fully onto the mandrel before powering the tool, and inspect the roll for tears or separation before each use. Always wear appropriate eye and respiratory protection when operating abrasive rotary tools.
