Merit Abrasives 08834180078 Cartridge Roll 36 Grit 1/4 in

Product Description

The MERIT ABRASIVES 08834180078 is a straight cartridge roll designed for precision grinding and deburring in tight interior contours, slots, and bores. Built with an aluminum oxide abrasive at 36 grit, this roll delivers aggressive material removal suited for very coarse stock removal on ferrous and non-ferrous metals. At 1/4 inch in diameter, it fits standard mandrels used in die grinders and rotary tools. Metalworkers, machinists, and fabricators reach for this type of roll when they need to clean up weld seams, smooth bore interiors, or remove heavy burrs in confined geometry that flat abrasives cannot reach.

This cartridge roll is intended for use in industrial and shop environments where die grinders or rotary tools are standard equipment. The straight profile makes it the right choice for cylindrical or straight-walled internal surfaces. Very coarse 36 grit is appropriate for rapid stock removal and initial surface conditioning before moving to finer finishing stages. It is well-suited to metal fabrication, tool and die work, maintenance repair, and general shop operations where efficient material removal in restricted areas is required.

Key Features

• Aluminum oxide abrasive construction provides consistent cut rate on ferrous and non-ferrous metals
• 36 grit very coarse grade for aggressive stock removal and heavy burr elimination
• 1/4 inch diameter fits standard mandrels in die grinders and rotary hand tools
• Straight cartridge profile targets cylindrical bores, slots, and confined interior surfaces
• Sold individually with a minimum order quantity of 100 units for shop and production use

Compatibility

Designed for use with standard 1/4 inch mandrels compatible with die grinders and rotary tools used in metal fabrication and finishing applications.

Installation Notes

Installation is performed by machinists or metal fabricators using a compatible mandrel secured in a die grinder or rotary tool. Ensure the tool is powered off and disconnected from its air or electrical supply before mounting or removing the cartridge roll. Confirm the mandrel diameter matches the roll bore before use, and do not exceed the maximum RPM rating of the abrasive or the tool. Eye protection and appropriate PPE are required when operating rotary abrasives.
