3M 7100127589 Ceramic Cartridge Roll 80 Grit 3/8 in

Product Description

The 3M 7100127589 is a ceramic grain abrasive cartridge roll built for aggressive material removal in tight or contoured areas. Constructed on an X-weight cloth backing, it delivers the durability needed for demanding grinding and blending operations on metal and similar hard materials. A resin bond system provides heat resistance during extended use, and an integrated grinding aid promotes cooler cutting action to extend abrasive life and reduce workpiece discoloration. At 80 grit, this roll targets stock removal and surface conditioning where a coarser cut is required before finishing passes.

Cartridge rolls in this configuration are used by metalworkers, tool-and-die technicians, and fabrication shops for internal diameter grinding, port work, weld blending, and deburring in areas that larger abrasives cannot reach. The 3/8-inch diameter and 1-1/2-inch length make this roll well-suited for use with mandrel-mounted die grinders and similar rotary tools in both production and maintenance settings.

Key Features

• Ceramic grain construction for high cut rate and extended abrasive life
• X-weight cloth backing provides strength and flexibility under grinding pressure
• Resin bond system resists heat generated during aggressive grinding
• Grinding aid promotes cooler cutting action, reducing heat damage to workpiece
• 80 grit for efficient stock removal and weld blending
• Compact 3/8-inch x 1-1/2-inch x 1/8-inch profile for access in tight or contoured areas

Compatibility

Designed for use with standard mandrel-mounted die grinders and rotary tools accepting 1/8-inch shank mandrels. Suitable for grinding and blending operations on ferrous and non-ferrous metals in general fabrication and maintenance environments.

Installation Notes

Cartridge rolls are installed by a qualified operator onto a compatible threaded or tapered mandrel sized to match the roll ID before mounting in a pneumatic or electric die grinder. Confirm the tool RPM rating meets or exceeds the abrasive product maximum operating speed before use. Wear appropriate PPE including eye protection and gloves when operating rotary abrasives. Inspect the roll for damage before each use and discard any roll showing signs of unraveling or core separation.
