Merit Abrasives 08834180026 Cartridge Roll 120 Grit 3/16 in

Product Description

The MERIT ABRASIVES 08834180026 is a straight cartridge roll designed for precision grinding and deburring in tight spaces and contoured surfaces. Built with aluminum oxide abrasive, this roll delivers consistent stock removal at 120 grit, placing it in the fine grade range ideal for smoothing and light material removal. The 3/16 inch diameter allows it to reach into narrow bores, slots, and cavities where flat abrasives cannot. Machinists, fabricators, and maintenance technicians use these rolls with mandrel-mounted rotary tools, die grinders, and flex-shaft machines to refine surfaces and remove burrs on metal, wood, and composite materials.

This cartridge roll suits applications in metal fabrication shops, tool and die work, welding cleanup, and general finishing operations. The fine 120 grit is well-suited for intermediate finishing passes after coarser stock removal, producing a smooth surface ready for further processing or coating. Its straight profile makes it appropriate for cylindrical bores and straight-walled recesses rather than tapered or radiused profiles.

Key Features

• Aluminum oxide abrasive grain for consistent cut rate on ferrous and non-ferrous metals
• 120 grit fine grade for smooth finishing and light deburring
• 3/16 inch diameter for access to narrow bores and confined cavities
• Straight profile maintains consistent contact in cylindrical and straight-walled openings
• Compatible with standard cartridge roll mandrels used on die grinders and rotary tools

Compatibility

Designed for use with standard mandrel-style cartridge roll holders on die grinders, rotary tools, and flex-shaft machines. Specific compatible equipment or replacement part numbers were not identified in the available product data.

Installation Notes

A licensed machinist or fabricator should mount the cartridge roll onto a properly sized mandrel before use. Ensure the die grinder or rotary tool is powered off and unplugged before changing rolls. Do not exceed the maximum RPM rating of the tool or the roll. Inspect the roll for tears or separation before each use and replace if worn unevenly to avoid tool runout.
