Merit Abrasives 08834181749 Cartridge Roll 180 Grit

Product Description

The MERIT ABRASIVES 08834181749 is a full taper cartridge roll designed for precision deburring, blending, and finishing in tight bores, slots, and contoured surfaces. Built with aluminum oxide abrasive at 180 grit, this roll falls in the very fine range, making it well-suited for final-stage surface preparation and light stock removal. The roll measures 1/2 inch in diameter by 1-1/2 inches in length and accepts a 1/8 inch pilot hole mandrel. It is commonly used by machinists, fabricators, and finishing technicians working with portable die grinders or drill presses on metal and composite workpieces.

This cartridge roll is intended for use in industrial and maintenance environments where internal surface finishing is required. Typical applications include cleaning up weld areas inside tubing, smoothing bore interiors, and preparing mating surfaces prior to assembly. The full taper geometry allows the abrasive to conform progressively to the workpiece as the roll wears, maintaining consistent contact throughout its usable life. It is sold individually but carries a minimum order quantity of 100 units, making it appropriate for shop stock replenishment and production use.

Key Features

• 180 grit aluminum oxide abrasive for very fine finishing and blending

Compatibility

Designed as an OEM-style replacement cartridge roll for use with standard 1/8 inch pilot mandrels compatible with portable rotary tools and die grinders accepting this roll size.

Installation Notes

Cartridge rolls are installed by threading the pilot hole onto a compatible mandrel before chucking the mandrel into the rotary tool. Ensure the tool is powered off and fully stopped before changing rolls. Verify mandrel and roll size compatibility before operation, and confirm that the tool RPM rating meets or exceeds the roll manufacturer guidelines. Eye protection and appropriate PPE should be used during all grinding and finishing operations.
