Merit Abrasives 08834180232 Cartridge Roll 3/8 in 80 Grit

Product Description

The MERIT ABRASIVES 08834180232 is a straight cartridge roll designed for precision grinding, deburring, and surface finishing in tight spaces such as bores, slots, and contoured surfaces. The roll features an aluminum oxide abrasive at 80 grit, classifying it as a medium grade suitable for moderate material removal and blending on ferrous and non-ferrous metals. With a 3/8-inch diameter, it fits mandrel-mounted setups used in die grinders and drill presses. Metalworkers, tool-and-die technicians, and fabricators rely on this style of cartridge roll where flat abrasives cannot reach.

This cartridge roll is well suited for production and job-shop environments where internal diameter finishing, weld blending, and edge chamfering are routine tasks. The 80-grit aluminum oxide construction provides a balance between cut rate and surface finish, making it appropriate for intermediate stock removal before moving to finer grits. It is sold individually but carries a minimum order quantity of 100 units, making it a staple stocking item for shops with consistent abrasive consumption.

Key Features

Compatibility

Designed as an OEM-style replacement consumable for use with standard straight cartridge roll mandrels compatible with 3/8-inch diameter rolls in die grinders and drill press applications.

Installation Notes

Installation is performed by metalworking technicians using a compatible threaded or collet-style mandrel mounted in a die grinder or similar rotary tool. Ensure the mandrel diameter matches the cartridge roll bore before seating the roll fully onto the mandrel. Always confirm the tool RPM rating does not exceed the maximum rated speed of the abrasive roll before operation. Wear appropriate eye protection and follow shop safety protocols when using rotary abrasives.
