Merit Abrasives 08834180463 Cartridge Roll 180 Grit 3/4 in

Product Description

The MERIT ABRASIVES 08834180463 is a straight cartridge roll designed for precision deburring, blending, and finishing in tight contours and bores. This roll uses aluminum oxide abrasive bonded to a spiral-wound paper cartridge that fits standard mandrels. At 180 grit, it falls in the very fine grade range, making it suited for light stock removal, surface preparation, and pre-finish smoothing on metal workpieces. At 0.035 pounds per unit, the roll is lightweight and easy to handle during high-cycle finishing operations. Machinists, tool-and-die workers, and metal fabricators are the primary users of this consumable abrasive.

Straight cartridge rolls at 3/4 inch diameter are commonly used in die grinders and portable drilling tools to access internal bores, ports, and recesses where flat or disc abrasives cannot reach. This roll is appropriate for ferrous and non-ferrous metals in both job shop and production environments. The 180 grit level is particularly useful for finishing passes on aluminum, steel, and stainless steel components where surface finish quality matters more than aggressive material removal.

Key Features

• Aluminum oxide abrasive construction for consistent cut and long service life on metal substrates
• 180 grit very fine grade delivers smooth surface finish with minimal scratch pattern
• 3/4 inch diameter fits standard cartridge roll mandrels for die grinders and rotary tools
• Straight cartridge profile provides uniform contact in bores, ports, and contoured surfaces
• Lightweight at 0.035 pounds per unit, reducing operator fatigue in repetitive finishing tasks

Compatibility

Designed as a standard straight cartridge roll for use with compatible mandrels in die grinders, straight grinders, and other rotary finishing tools that accept 3/4 inch diameter cartridge rolls.

Installation Notes

Cartridge rolls are installed by a machinist or fabricator onto a tapered or expanding mandrel that matches the roll bore diameter. Ensure the mandrel is fully tightened before operating the tool. Always verify that the tool RPM rating does not exceed the maximum RPM rating of the abrasive roll. Wear appropriate eye and face protection when operating rotary abrasives, and inspect the roll for damage or unraveling before each use.
