Merit Abrasives 08834182338 Cartridge Roll Set 50 Pc

Product Description

The MERIT ABRASIVES 08834182338 is a 50-piece aluminum oxide cartridge roll set designed for deburring, blending, and finishing in tight-radius bores, slots, and contoured surfaces. The set includes rolls in 60, 80, and 120 grit, covering medium and fine grades in a single kit. Four mandrels are included so rolls can be mounted directly to a die grinder or rotary tool without separate hardware. This set is well suited to machinists, fabricators, metal finishing technicians, and maintenance trades who need consistent material removal across multiple grit stages without sourcing components individually.

Aluminum oxide abrasive construction makes these rolls suitable for use on ferrous metals, aluminum, brass, and harder plastics. Typical applications include interior weld cleanup, cylinder bore prep, port matching, and finish work on formed or cast components. The three-grit progression allows the user to step from aggressive stock removal at 60 grit through 80 grit blending to a finer 120 grit surface finish without swapping to a different abrasive system. The included mandrels reduce setup time across the full set.

Installation Notes

Cartridge rolls are installed by a machinist or metal finishing technician using the included mandrels. Ensure the rotary tool or die grinder is powered off and unplugged before mounting or changing rolls. Secure the roll firmly on the mandrel per the mandrel manufacturer guidance to prevent slippage during operation. Always wear appropriate PPE including eye protection and a dust mask when working with abrasive products.
