Merit Abrasives 08834180236 Cartridge Roll 3/8in 180 Grit

Product Description

The MERIT ABRASIVES 08834180236 is a straight cartridge roll designed for precision abrasive work in tight bores, slots, and contoured surfaces. Built with an aluminum oxide abrasive at 180 grit, this roll falls in the very fine grade range, making it well-suited for finishing and light deburring passes where surface quality matters. The rolled construction allows it to be mounted on a mandrel and used with a die grinder or rotary tool. At 3/8 inches in diameter, it fits smaller-bore applications where larger wheels cannot reach. Each unit is sold individually and is a consumable replacement item for ongoing finishing operations.

This cartridge roll is used in metal fabrication, tool and die work, welding cleanup, and general metalworking applications. It is appropriate for use on ferrous and non-ferrous metals where a controlled, fine finish is required. Typical install scenarios include port work, cylinder bore finishing, weld seam blending, and surface prep in areas with restricted access. The 180 grit aluminum oxide construction is also used in woodworking and composite finishing where a smooth, consistent scratch pattern is needed before final surface treatment.

Installation Notes

Straight cartridge rolls are installed by threading the roll onto a matching mandrel and securing it per the mandrel manufacturer instructions. Always confirm the tool RPM rating does not exceed the maximum rated speed of the abrasive before use. Wear appropriate eye and face protection, and inspect the roll for damage or unraveling before mounting. Do not use a damaged or deformed roll.
