Merit Abrasives 08834180383 Cartridge Roll 5/8 in 80 Grit

Product Description

The MERIT ABRASIVES 08834180383 is a straight cartridge roll designed for precision deburring, blending, and finishing in tight contours, bores, and hard-to-reach areas. Built with aluminum oxide abrasive at 80 grit, this roll delivers medium-grade stock removal on ferrous and non-ferrous metals, wood, and composites. At 5/8 inch in diameter, it fits standard mandrel setups used with die grinders, drill presses, and flexible shaft tools. The aluminum oxide grain is well-suited to consistent cut rates under moderate pressure, making it a reliable choice for production finishing and surface prep work.

This cartridge roll is used in metalworking, fabrication, and maintenance applications where rotary file or flap wheel access is insufficient. Common scenarios include blending weld seams inside pipe joints, smoothing bore openings, and finishing contoured profiles on machined components. It is appropriate for both shop and field use where a die grinder or similar rotary tool is available. Trade machinists, fabricators, maintenance technicians, and toolroom operators are the primary installers and users of this product.

Key Features

• Aluminum oxide abrasive provides consistent, moderate-aggression stock removal across a wide range of materials
• 80 grit medium grade balances cut rate and surface finish for deburring and blending tasks
• 5/8 inch diameter fits standard mandrel configurations for die grinders and rotary tools
• Straight cartridge roll geometry accesses bores, contours, and tight internal profiles
• Lightweight at 0.03 pounds per unit, minimizing tool balance disruption during extended use

Compatibility

Designed as an OEM-style replacement cartridge roll for use with standard mandrels sized to accept 5/8 inch diameter straight cartridge rolls on die grinders, drill presses, and flexible shaft machines.

Installation Notes

Cartridge rolls are installed by a machinist or fabricator onto a matching arbor mandrel threaded or tapered to the roll bore. Ensure the mandrel diameter matches the roll bore before seating the roll fully onto the arbor. Inspect the roll for tears or separation before use, and never exceed the maximum RPM rating of the mandrel or tool. Eye protection and appropriate PPE are required whenever operating rotary abrasives.
