Merit Abrasives 08834180461 Straight Cartridge Roll 120 Grit

Product Description

The MERIT ABRASIVES 08834180461 is a straight cartridge roll designed for precision grinding, deburring, and surface finishing in tight or contoured areas. Built with an aluminum oxide abrasive grain at 120 grit, this roll delivers a fine-grade finish suitable for blending weld seams, cleaning up bores, and smoothing interior surfaces on metal workpieces. At 3/4 inch in diameter with a 3/16 inch pilot hole, it fits standard mandrels used in die grinders and drill presses. Weighing just 0.035 pounds, it is a lightweight consumable suited for repetitive production work or detailed hand finishing by machinists, fabricators, and maintenance professionals.

This cartridge roll is intended for use on ferrous and non-ferrous metals in both production shop and maintenance environments. The 120 grit aluminum oxide construction makes it appropriate for intermediate-to-fine finishing passes where material removal must be controlled. Typical applications include cleaning up drilled or reamed holes, blending inside radii, and finishing weld joints in areas inaccessible to flat abrasives. It is used by machinists, metal fabricators, welders, and industrial maintenance technicians working on fixtures, castings, tubing, and structural components.
