3M 7010309052 Straight Cartridge Roll 60 Grit 5/8 in

Product Description

The 3M 7010309052 is a straight cartridge roll designed for precision abrasive work on metal, wood, and composite surfaces. Built with aluminum oxide grain on a cloth backing, it delivers consistent medium-grade cutting action at 60 grit. The straight cartridge profile seats into mandrel-mounted holders used on die grinders, straight grinders, and similar rotary tools. It is rated to a maximum of 16,000 RPM, making it suitable for fast material removal in tight bores, contoured slots, and hard-to-reach areas. Machinists, fabricators, and tool-and-die technicians are the primary users of this type of abrasive consumable.

This cartridge roll is suited for deburring, blending, and finishing operations in metalworking and fabrication environments. It performs well in bore finishing, port matching, weld blending, and surface preparation tasks where a small-diameter abrasive is required. The cloth backing provides flexibility and resistance to tearing under load, making it effective on both ferrous and non-ferrous metals as well as some hard plastics and composites. It is sold individually but requires a minimum order of 100 units per purchase.

Installation Notes

Installation is performed by a machinist or abrasive tool operator. Before mounting, ensure the grinder is disconnected from its air supply or power source. Thread the cartridge roll onto the appropriate mandrel per the tool manufacturer's instructions and verify it is fully seated before operation. Never exceed the 16,000 RPM maximum speed rating marked on the product.
