3M 7100085778 Cartridge Roll 80 Grit 0.375x1.5x0.125 Inches

Product Description

The 3M 7100085778 is a full tapered aluminum oxide cartridge roll designed for precision grinding, deburring, and surface blending on metal and other hard materials. Built on an X-weight cloth backing, this roll delivers the durability and flexibility needed for demanding material removal applications. The resin bond construction provides heat resistance, helping the abrasive maintain performance through extended use. At 80 grit, the roll removes material aggressively while leaving a consistent scratch pattern suitable for follow-on finishing operations. These rolls are a standard consumable for die grinders and cartridge roll mandrels used in fabrication and maintenance environments.

This cartridge roll is suited for use in metalworking, fabrication shops, weld blending, and maintenance repair operations. The full taper geometry allows the roll to conform to contoured surfaces and reach into grooves, ports, and tight radii where flat abrasives cannot. It is commonly used by machinists, pipefitters, tool and die workers, and general metalworking tradespeople who require consistent, repeatable abrasive performance on both ferrous and non-ferrous workpieces.

Key Features

• Aluminum oxide abrasive mineral for reliable cutting action on metal surfaces
• X-weight cloth backing provides durability and resistance to tearing under load
• Resin bond construction resists heat buildup during aggressive material removal
• Full taper geometry conforms to contoured and recessed surfaces
• 80 grit for aggressive stock removal with a consistent scratch pattern
• Compact 0.375 inches x 1.5 inches x 0.125 inches size fits standard cartridge roll mandrels

Compatibility

Designed for use with standard cartridge roll mandrels on die grinders and rotary tools sized to accept 0.125-inch shank cartridge rolls.

Installation Notes

Installation and removal of cartridge rolls should be performed with the tool unplugged or the air supply disconnected. Secure the roll onto the appropriate mandrel following the mandrel manufacturer's torque guidance and inspect the roll for tears or separation before use. Always operate within the maximum RPM rating of the abrasive roll and wear appropriate eye and face protection. These rolls are a consumable item and should be discarded when the abrasive layer is worn through to the backing.
