Merit Abrasives 08834180499 Cartridge Roll 120 Grit 3/4 in

Product Description

The MERIT ABRASIVES 08834180499 is a straight cartridge roll designed for precision deburring, blending, and finishing on metal and composite surfaces. It uses an aluminum oxide abrasive at 120 grit, placing it in the fine grade range — well suited for controlled material removal and surface prep before coating or inspection. At 3/4 inch in diameter, it fits mandrel-driven die grinders and pneumatic finishing tools commonly used in fabrication, maintenance, and toolroom settings. Machinists, welders, and metalworking technicians reach for this style of roll when working bores, slots, contoured edges, and hard-to-reach interior surfaces.

This cartridge roll is a standard fit for straight mandrel setups used in industrial finishing and light material removal applications. It is appropriate for use on ferrous and non-ferrous metals in both shop and field environments. The 120 grit aluminum oxide construction suits finish blending after grinding, weld seam cleanup, and prep work ahead of painting or protective coating. It is sold individually, with a minimum order quantity of 100 units per order.

Installation Notes

Installation is performed by metalworking or fabrication technicians using a compatible straight mandrel sized for the 3/4 inch roll diameter. Ensure the die grinder or rotary tool is powered off and depressurized before mounting or removing the roll. Follow the tool manufacturer's mandrel torque and RPM rating to avoid roll slippage or abrasive failure at speed. Inspect the roll for tears or uneven wear before each use.
