Merit Abrasives 08834181719 Taper Cartridge Roll 180 Grit

Product Description

The MERIT ABRASIVES 08834181719 is a full taper cartridge roll designed for precision deburring, blending, and surface finishing in tight bores, slots, and contoured workpieces. It uses aluminum oxide as the abrasive material, delivering consistent cut and finish across ferrous and non-ferrous metals. At 180 grit, this roll falls in the very fine grade range, making it well suited for finishing passes where surface quality matters. The full taper geometry allows the roll to conform to irregular interior shapes, reaching areas that flat or straight abrasives cannot. Each unit is sold individually and is sized for use with standard mandrel-driven rotary tools and die grinders.

This cartridge roll is used in metalworking, fabrication, and maintenance applications where internal surfaces require fine finishing. Typical scenarios include port finishing, weld blending inside tubing, and removing tooling marks from bored or reamed holes. The very fine 180 grit designation makes it appropriate for final-stage work after coarser material removal is complete. It is commonly used by machinists, metal fabricators, and maintenance technicians working with hand-held pneumatic or electric rotary tools.

Key Features

• Full taper geometry conforms to contoured bores and irregular interior surfaces
• 180 grit aluminum oxide abrasive for very fine surface finishing
• Maximum roll diameter of 3/8 inches fits standard small-bore applications
• Sold as individual units with a minimum order quantity of 100
• Aluminum oxide construction provides consistent cut on ferrous and non-ferrous metals

Compatibility

Designed as an OEM-style replacement consumable for use with standard mandrel-driven rotary tools and die grinders that accept cartridge roll abrasives in the 3/8 inch diameter range.

Installation Notes

Cartridge rolls are installed by a machinist or fabricator onto a compatible tapered or straight mandrel secured in a rotary tool or die grinder. Confirm the mandrel size matches the roll bore before mounting, and ensure the tool is fully powered off and depressurized before changing abrasives. Follow applicable shop safety practices including eye protection and RPM rating verification to avoid abrasive failure during use.
