3M 7100149032 Ceramic Cartridge Roll 60 Grit 3/8x1-1/2x1/8 in

Product Description

The 3M 7100149032 is a ceramic grain abrasive cartridge roll designed for aggressive material removal and precision grinding on metal and hard surfaces. Built on an X-weight cloth backing and resin bonded for heat resistance, this roll delivers consistent cut and durability through demanding applications. It measures 3/8 inches in diameter by 1-1/2 inches in length with a 1/8 inches arbor hole, and carries a 60-grit rating suited for stock removal and surface conditioning. A built-in grinding aid promotes cooler grinding, reducing heat buildup and extending the life of the abrasive.

This cartridge roll is used in die grinder and mandrel applications across metal fabrication, welding shops, and industrial maintenance environments. It is well suited for deburring, blending welds, and grinding in tight or contoured areas where flat abrasives cannot reach. The compact cylindrical form factor allows access to slots, bores, and recessed surfaces. Machinists, fabricators, and maintenance technicians typically use this style of roll for finishing operations on steel, stainless, and other hard alloys.

Key Features

• Ceramic abrasive grain for fast, aggressive cut and extended service life
• X-weight cloth backing for durability under high-pressure grinding
• Resin bond construction resists heat generated during heavy stock removal
• Integrated grinding aid promotes cooler grinding and reduces loading
• 60-grit rating suited for stock removal and initial surface blending
• 3/8 inches x 1-1/2 inches x 1/8 inches form factor fits standard mandrel setups

Compatibility

Designed for use with standard 1/8 inches shank mandrels in die grinders and rotary tools used in metal fabrication and industrial grinding applications.

Installation Notes

Installation is performed by threading the cartridge roll onto a compatible 1/8 inches mandrel and securing it according to the mandrel manufacturer's guidelines. Ensure the grinder is powered off and disconnected before mounting or removing the roll. Operate within the maximum RPM rating of the abrasive roll and mandrel assembly. Inspect the roll for damage or wear before each use and replace if tears, fraying, or excessive wear are present.
