Merit Abrasives 08834180379 Straight Cartridge Roll 36 Grit

Product Description

The MERIT ABRASIVES 08834180379 is a straight cartridge roll designed for precision abrasive finishing in tight bores, slots, and contoured surfaces. It measures 0.625 inches in maximum roll diameter and 1.5 inches in overall length, with a 3/16 inch pilot hole diameter for secure mandrel mounting. At 36 grit, this roll falls in the very coarse grade range, making it well suited for aggressive material removal and initial surface conditioning on metal workpieces. Machinists, tool-and-die workers, and metalworking tradespeople install these rolls as part of standard deburring and blending operations.

Straight cartridge rolls like the 08834180379 are used in die grinders, drill presses, and flex-shaft machines for internal diameter finishing, weld blending, and port work on metal components. This roll is appropriate for ferrous and non-ferrous metals in both production shop and maintenance environments. The very coarse 36 grit is particularly effective in early-stage surface prep where fast stock removal is the priority before progressing to finer grits.

Key Features

• 36 grit very coarse grade for aggressive stock removal and rapid surface conditioning

Compatibility

Designed for use with standard mandrels accepting a 3/16 inch pilot hole, compatible with die grinders, drill presses, and flex-shaft machines commonly used in metal finishing and fabrication work.

Installation Notes

Installation is performed by metalworking tradespeople using a compatible mandrel sized to the 3/16 inch pilot hole. Ensure the die grinder or rotary tool is powered off and unplugged before mounting or removing the cartridge roll. Do not exceed the tool or mandrel RPM rating. Inspect the roll for wear or delamination before each use and replace when the abrasive is exhausted or the roll loses its form.
