Merit Abrasives 08834180212 Cartridge Roll 3/8 in 50 Grit

Product Description

The MERIT ABRASIVES 08834180212 is a straight cartridge roll abrasive designed for precision grinding, deburring, and surface finishing in tight or contoured areas. Built with aluminum oxide abrasive grain at 50 grit, this roll delivers coarse-grade material removal on ferrous and non-ferrous metals, wood, and composites. At 3/8 inch in diameter, it fits standard mandrels used in die grinders and rotary tools. Machinists, metal fabricators, and tool-and-die technicians install this type of cartridge roll for internal bore work, weld cleanup, and contour blending where flat abrasives cannot reach.

This cartridge roll is suited for use in industrial and shop environments where consistent stock removal is needed in recessed or curved surfaces. Typical applications include porting work, keyway cleanup, and finishing inside drilled or cast openings. The coarse 50-grit rating makes it appropriate for aggressive material removal rather than fine finishing or polishing passes. It is sold individually, with a minimum order quantity of 100 units per order placement.

Key Features

• Aluminum oxide abrasive grain for durable cutting action on metal and wood surfaces

Compatibility

Designed as a standard straight cartridge roll for use with compatible 3/8 inch mandrels in die grinders, drill presses, and rotary tools used in metal fabrication and finishing applications.

Installation Notes

Cartridge rolls are installed by threading the roll onto a matching mandrel and tightening per the mandrel manufacturer's guidance. Ensure the rotary tool or die grinder is powered off and disconnected from the air supply or electrical source before mounting or removing abrasive rolls. Operators should wear appropriate eye protection and follow shop safety procedures when working with abrasive tooling. Do not exceed the maximum RPM rating of the mandrel or tool in use.
