Merit Abrasives 08834180307 Straight Cartridge Roll 60 Grit

Product Description

The MERIT ABRASIVES 08834180307 is a straight cartridge roll designed for precision grinding, deburring, and surface blending in tight contours and bore work. Built with aluminum oxide abrasive at 60 grit, this medium-grade roll delivers consistent stock removal on ferrous metals, castings, and general-purpose workpieces. The straight profile maintains uniform contact along the full length of the roll, making it effective for parallel bore walls and internal chamfers. With a maximum speed rating of 23,000 RPM, it is compatible with standard die grinders and rotary tools used in machining, fabrication, and maintenance applications. Licensed machinists, tool and die makers, and metal fabricators are the primary users of this consumable.

This cartridge roll is suited for metal finishing operations in both production and job-shop environments. It excels in applications requiring controlled material removal in recessed areas, slots, and curved internal surfaces where flat abrasive media cannot reach. The 0.5-inch diameter fits mandrels commonly found in die grinder setups used in automotive, aerospace, and general metalworking shops. It is sold individually and requires a compatible mandrel for mounting. Minimum order quantity is 100 units, making this roll appropriate for shops that consume abrasives at a production rate.

Installation Notes

Installation requires a compatible straight cartridge roll mandrel; ensure the mandrel is securely threaded and the roll is fully seated before operation.

Inspect the roll for tears or deformation before each use and replace immediately if damage is found.
