Merit Abrasives 08834180488 Cartridge Roll 3/4 in 120 Grit

Product Description

The MERIT ABRASIVES 08834180488 is a straight cartridge roll designed for precision deburring, blending, and surface finishing in tight spaces and contoured areas. Built with aluminum oxide abrasive, this roll delivers consistent stock removal on ferrous and non-ferrous metals. At 120 grit, it falls in the fine grade range, making it well suited for light material removal and surface refinement where a smooth finish is the goal. Straight cartridge rolls mount on a mandrel and are driven by a die grinder or similar rotary tool, making them a go-to consumable for machinists, fabricators, and maintenance technicians working on interior bores, slots, and radiused surfaces.

This cartridge roll is used in metalworking, fabrication shops, and industrial maintenance applications. The straight profile makes it effective for working inside tubes, ports, and cylindrical cavities where a flat or tapered profile would not make full contact. It is appropriate for use on steel, stainless steel, aluminum, and similar materials. The fine 120 grit finish is typically applied after coarser stock removal passes to refine surface texture before final inspection or coating prep.

Key Features

• Aluminum oxide abrasive for reliable performance on ferrous and non-ferrous metals
• 120 grit fine grade for surface refinement and light stock removal
• 3/4 inch diameter straight profile for consistent contact in bores and contoured areas
• Mandrel-mount design compatible with standard die grinders and rotary tools
• Sold individually with a minimum order quantity of 100 units

Compatibility

Designed as an OEM-style replacement consumable for use with standard mandrel-driven die grinders and rotary finishing tools that accept straight cartridge roll configurations.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a compatible mandrel and die grinder. Ensure the tool is powered off and the air supply or power source is fully disconnected before changing rolls. Thread the cartridge roll onto the mandrel and confirm it is seated securely before operation. Always operate within the tool and abrasive manufacturer's rated RPM limits to prevent roll failure.
