Merit Abrasives OLD08834180216 Cartridge Roll 120 Grit

Product Description

The MERIT ABRASIVES OLD08834180216 is a straight cartridge roll designed for precision grinding, deburring, and surface blending in tight interior contours and bores. Built with aluminum oxide abrasive on a paper-core mandrel roll, it delivers consistent stock removal on ferrous and non-ferrous metals. At 3/8 inches in diameter and rated at 120 grit (Fine grade), this roll suits finish-stage work where controlled material removal and smooth surface texture are the priority. Machinists, tool and die technicians, and metal fabricators reach for this style of roll when working die cavities, tube interiors, and complex curved surfaces that flat abrasives cannot reach.

Straight cartridge rolls like the OLD08834180216 are used in portable die grinders and rotary tool setups across production machining, weld blending, and mold and die finishing applications. The 120 grit Fine grade positions this roll for final shaping and surface preparation work rather than heavy stock removal. It is suited for both bench-top and in-place grinding tasks in metalworking shops, aerospace maintenance operations, and general fabrication environments.

Key Features

• Aluminum oxide abrasive grain for consistent cut on steel, iron, and non-ferrous metals
• 120 grit Fine grade for finish grinding and surface blending
• 3/8 inches diameter fits standard die grinder mandrels for interior bore and contour work
• Straight cartridge profile for uniform contact in cylindrical and contoured surfaces
• Sold individually — minimum order quantity is 100 units

Compatibility

Designed as an OEM-style replacement consumable for use with standard straight cartridge roll mandrels compatible with 3/8 inches diameter cartridge rolls in die grinder applications.

Installation Notes

Installation is performed by metalworking trades including machinists and fabricators. Before mounting, ensure the die grinder or rotary tool is fully powered off and unplugged. Slide the cartridge roll onto a compatible straight mandrel and tighten the mandrel screw to secure the roll without over-compressing the paper core. Always verify the tool RPM rating does not exceed the maximum rated speed of the abrasive roll before operation.
