Merit Abrasives 08834180478 Cartridge Roll 3/4 in 80 Grit

Product Description

The MERIT ABRASIVES 08834180478 is a straight cartridge roll designed for precision deburring, blending, and finishing in tight or contoured areas. Built with aluminum oxide abrasive, this roll delivers consistent stock removal on ferrous and non-ferrous metals. At 3/4 inch diameter and 80 grit, it falls in the medium grade range, making it well suited for intermediate finishing work where aggressive material removal is needed without leaving deep scratch patterns. Machinists, fabricators, and maintenance technicians use these rolls in mandrel-driven die grinders and rotary tools for controlled surface refinement.

Straight cartridge rolls are commonly used in manufacturing, fabrication shops, and MRO environments. They are particularly effective for finishing bore IDs, slots, weld seams, and curved surfaces that flat abrasives cannot reach. The straight profile provides uniform contact along the length of the roll, making it a reliable choice for consistent finish quality in production or repair applications.

Key Features

• Aluminum oxide abrasive construction for durable cutting action on metal surfaces
• 80 grit medium grade for intermediate stock removal and surface blending
• 3/4 inch diameter straight profile for access to bores, slots, and contoured areas
• Compatible with standard mandrel-driven rotary tools and die grinders
• Consistent abrasive layer delivers repeatable finish results across the roll surface

Compatibility

Designed as an OEM-style replacement or standard consumable cartridge roll for use with mandrel-driven die grinders and rotary finishing tools accepting 3/4 inch diameter straight cartridge roll media.

Installation Notes

Cartridge rolls are installed by threading onto a compatible mandrel arbor; ensure the mandrel diameter matches the roll core before mounting. Power down the rotary tool and disconnect from the power source before changing rolls. Always verify the tool RPM rating does not exceed the maximum rated speed of the abrasive roll. Eye protection and appropriate PPE are required during operation per standard shop safety practices.
