Merit Abrasives 08834182400 Taper Cartridge Roll 120 Grit

Product Description

The MERIT ABRASIVES 08834182400 is a full taper cartridge roll designed for precision deburring, blending, and surface finishing in tight or contoured areas. Built with aluminum oxide abrasive at 120 grit, it delivers a fine cutting action suited for smoothing weld seams, cleaning bores, and finishing internal radii. The tapered profile allows the roll to conform to irregular surfaces and reach into recessed geometry that flat abrasives cannot access. Weighing 0.015 pounds per unit, it is a lightweight consumable intended for use on mandrel-style die grinders and rotary tools. Machinists, fabricators, and tool-and-die technicians are the primary users of this type of abrasive roll.

This cartridge roll is suited for metalworking applications in job shops, manufacturing facilities, and fabrication environments. It is commonly used on ferrous and non-ferrous metals where a fine finish is required after rough grinding or machining. The 120 grit aluminum oxide construction performs well on steel, aluminum, and cast iron surfaces. Typical install scenarios include finishing cylindrical ports, cleaning up drilled or reamed holes, and blending surface transitions prior to coating or assembly inspection.

Key Features

• Full taper profile conforms to contoured and recessed surfaces
• 120 grit aluminum oxide abrasive delivers a fine cutting action
• 3/8 inch maximum roll diameter fits standard cartridge roll mandrels
• Lightweight at 0.015 pounds, minimizing added load on pneumatic or electric die grinders
• Consistent grit distribution across the full taper for uniform stock removal

Compatibility

Designed for use with standard cartridge roll mandrels compatible with 3/8 inch maximum diameter cartridge rolls, as used on pneumatic and electric die grinders and rotary tools.

Installation Notes

Installation is performed by machinists or fabricators using a compatible mandrel inserted into a die grinder or rotary tool. Ensure the mandrel arbor matches the cartridge roll bore before mounting, and tighten securely per the mandrel manufacturer's guidance. Power down the tool and disconnect the air supply or electrical source before changing rolls. Always operate within the maximum RPM rating of both the roll and the tool to prevent abrasive failure.
