3M 7100080019 Cartridge Roll 240 Grit 0.25x1x0.125 in

Product Description

The 3M 7100080019 is an aluminum oxide abrasive 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 needed for demanding material removal tasks. Resin bonding holds the abrasive grain firmly through elevated heat conditions, extending usable life in continuous-use applications. At 240 grit, it is suited to fine finishing and light stock removal where surface quality matters. Installation and use require only a compatible mandrel-driven rotary tool or die grinder, making this a straightforward consumable for shop technicians and finishing professionals.

This cartridge roll is used in metalworking, fabrication, and surface prep applications across industrial and trade environments. The compact 0.25 inches by 1 inch by 0.125 inches form factor fits into tight contours, bores, and recesses where flat abrasive media cannot reach. It is commonly used in HVAC component fabrication, plumbing fitting prep, and general metal finishing by machinists and sheet metal workers requiring consistent fine-grit results in confined areas.

Key Features

• Aluminum oxide abrasive grain for reliable cut rate on ferrous and non-ferrous metals
• X-weight cloth backing provides durability and resistance to tearing under load
• Resin bond construction resists heat buildup during extended grinding sessions
• 240 grit designation delivers fine finishing and light surface blending
• Compact roll dimensions suit contoured surfaces, bores, and hard-to-reach areas

Compatibility

Designed for use with standard mandrel-driven rotary tools and die grinders that accept 0.125 inches shank cartridge rolls. Consult your tool manufacturer specifications to confirm mandrel size compatibility before use.

Installation Notes

Installation is performed by threading the roll onto a compatible tapered or straight mandrel and securing it according to the tool manufacturer guidelines. Ensure the rotary tool or die grinder is fully powered off and disconnected from its power source before changing abrasive rolls. Do not exceed the maximum RPM rating of the cartridge roll or the tool. Inspect the roll for damage before each use and replace immediately if tearing or unraveling is detected.
