3M 7100122978 Ceramic Cartridge Roll 80 Grit 3/8x1x1/8 in

Product Description

The 3M 7100122978 is a ceramic abrasive cartridge roll built for demanding material removal in tight spaces and contoured surfaces. It runs on an X-weight cloth backing, which provides the durability needed for heavy grinding and blending operations. The ceramic grain is resin bonded for heat resistance, and a built-in grinding aid promotes cooler cutting to reduce workpiece discoloration and extend abrasive life. At 80 grit, this roll is suited for aggressive stock removal before transitioning to finer finishing steps. It measures 3/8 inches in diameter by 1 inch in length with a 1/8 inch arbor hole.

This cartridge roll is used in die grinders and cartridge roll mandrels for weld blending, deburring, and surface prep on metal fabrication and repair work. The small diameter and cylindrical profile allow access to recessed weld joints, tube interiors, and other areas where flap wheels or fiber discs cannot reach. Typical users include metal fabricators, maintenance machinists, and industrial finishing technicians working on ferrous and non-ferrous metals.

Key Features

• Ceramic abrasive grain for aggressive, consistent stock removal
• X-weight cloth backing provides durability under high grinding pressure
• Resin bond construction resists heat buildup during extended use
• Grinding aid promotes cooler cutting and reduces loading
• 80 grit designation suits initial weld blending and surface prep steps
• 3/8 x 1 x 1/8 inch profile fits standard cartridge roll mandrels

Compatibility

Designed for use with standard 1/8 inch shank cartridge roll mandrels in pneumatic or electric die grinders used for metal grinding and finishing applications.

Installation Notes

Installation is performed by threading the cartridge roll onto a compatible mandrel until snug. Ensure the die grinder is disconnected from the air supply or power source before changing abrasives. Do not exceed the maximum RPM rating of the abrasive or the tool. Inspect the roll for damage before each use and replace immediately if tearing or separation is observed.
