3M 7010309046 Cartridge Roll 80 Grit 1x2x0.25 Inch

Product Description

The 3M 7010309046 is an aluminum oxide cartridge roll built for precision grinding and finishing in tight or contoured areas. Constructed on an X-weight cloth backing, this roll delivers durability and flexibility under load. The resin bond system provides heat resistance, helping the abrasive grain stay effective during extended use. At 80 grit, it removes material efficiently on metals and other hard surfaces. Licensed HVAC technicians, machinists, fabricators, and maintenance professionals use cartridge rolls like this one to reach bores, slots, and curved surfaces that flat abrasives cannot access.

This cartridge roll measures 1 inch in diameter by 2 inches in length with a 1/4 inch arbor hole. The X-weight cloth backing resists tearing under moderate to heavy pressure, making it suitable for deburring, blending, and surface prep on metal components including tubing, fittings, pipe ends, and welded joints. It is sold by the roll with a minimum order quantity of 100 rolls, which suits shop and service operations that consume abrasives regularly.

Installation Notes

Cartridge rolls are installed by a trained technician or skilled tradesperson onto a matching mandrel secured to a rotary tool or die grinder. Ensure the spindle speed of the tool does not exceed the rated maximum speed of the abrasive roll. Always wear appropriate eye and face protection when operating abrasive products. Inspect the roll for damage before each use and discard any roll showing tears, looseness, or uneven wear.
