Merit Abrasives 08834180253 Cartridge Roll 120 Grit 3/8 in

Product Description

The MERIT ABRASIVES 08834180253 is a straight cartridge roll designed for precision deburring, blending, and finishing in tight bores, slots, and contoured surfaces. Built with aluminum oxide abrasive on a 3/8-inch maximum roll diameter and a 2-inch overall length, this roll delivers consistent cutting action across ferrous and non-ferrous metals. The 120-grit designation places it in the fine grade range, making it well suited for surface preparation work where controlled material removal and a smooth finish are both priorities. A 1/8-inch pilot hole diameter allows secure mandrel mounting.

This cartridge roll is used by machinists, tool-and-die workers, metal fabricators, and maintenance technicians working with portable die grinders and drill presses. Typical applications include finish work on weld beads, deburring drilled holes, and blending inside radii on machined components. The straight configuration is ideal for cylindrical bores and straight-walled recesses where a tapered roll would not maintain consistent contact.

Key Features

• 120-grit aluminum oxide abrasive for fine-grade material removal and surface blending
• Straight cartridge roll profile maintains uniform contact in cylindrical bores and slots
• 3/8-inch maximum roll diameter suits tight internal geometries
• 2-inch overall length provides reach into recessed areas
• 1/8-inch pilot hole for secure mandrel mounting on standard die grinder arbors

Compatibility

Designed as an OEM-style replacement or direct-use abrasive roll compatible with standard 1/8-inch mandrel arbors used in pneumatic and electric die grinders.

Installation Notes

Installation is performed by threading the cartridge roll onto a matching 1/8-inch mandrel arbor and tightening per the mandrel manufacturer's instructions. Ensure the die grinder is disconnected from the air supply or power source before changing abrasive accessories. Inspect the roll for damage before use and never exceed the maximum RPM rating of the mandrel or grinder. Eye protection and appropriate hand protection should be worn during operation per standard shop safety practices.
