Merit Abrasives 08834182105 Cartridge Roll Set 50pc

Product Description

The MERIT ABRASIVES 08834182105 is a 50-piece aluminum oxide cartridge roll set designed for use with rotary tools, die grinders, and mandrel-mount setups. The set includes three grit levels — 60, 80, and 120 — covering medium and fine grades for deburring, blending, and surface finishing on metal, wood, and composites. Aluminum oxide abrasive is a durable, self-sharpening media well suited to general-purpose stock removal and finishing tasks in shop and field environments. The variety of grits in a single set reduces the need for multiple purchases across a finishing progression.

This cartridge roll set is appropriate for use in metal fabrication, HVAC duct work, welding prep and cleanup, and general mechanical service where internal bore finishing or contoured surface work is required. The 60-grit rolls handle initial stock removal and weld bead blending, the 80-grit rolls bridge to intermediate finishing, and the 120-grit rolls provide a refined surface ready for coating or inspection. The set suits production shops, maintenance technicians, and trade professionals who cycle through multiple grits in a single workflow.

Installation Notes

Cartridge rolls are installed by threading onto a compatible mandrel following the tool manufacturer's torque and speed guidelines. Ensure the rotary tool or die grinder is fully powered down and disconnected from the air supply or electrical source before changing rolls. Follow applicable shop safety practices including eye protection and guarding appropriate to the RPM rating of the tool. Do not exceed the maximum RPM rating of the cartridge roll for the tool in use.
