Merit Abrasives OLD08834180214 Cartridge Roll 80 Grit 3/8 in

Product Description

The MERIT ABRASIVES OLD08834180214 is a straight cartridge roll designed for precision grinding, deburring, and surface finishing in tight spaces and contoured areas. Built with aluminum oxide abrasive at 80 grit, this medium-grade roll delivers consistent stock removal on ferrous and non-ferrous metals. At 3/8 inch in diameter, it mounts to mandrel-driven rotary tools and die grinders commonly used by machinists, fabricators, and maintenance technicians. The aluminum oxide grain provides reliable cut rate and durability across a range of materials, making this roll a practical choice for production finishing and weld blending applications.

This cartridge roll is suited for use in metalworking shops, fabrication facilities, and maintenance environments where rotary file or die grinder access is required in bores, slots, and curved surfaces. The straight profile accommodates cylindrical and flat-surface applications where a consistent abrasive contact area is needed. It is sold individually and typically ordered in quantities of 100 units to maintain supply continuity in high-use production settings.

Installation Notes

Installation is performed by qualified machinists or abrasive tool operators. Ensure the rotary tool or die grinder is fully powered down and disconnected from its power source before mounting or removing the cartridge roll. The roll must be seated fully onto a correctly sized mandrel and tightened per the mandrel manufacturer guidelines before operation. Inspect the roll for tears or separation before each use and do not exceed the tool or mandrel maximum RPM rating.
