3M 7010363874 Straight Cartridge Roll 120 Grit 3/8 in

Product Description

The 3M 7010363874 is a straight cartridge roll designed for precision abrasive work in tight or contoured areas. It uses aluminum oxide grain bonded to a cloth backing, delivering consistent stock removal and finishing performance across ferrous and non-ferrous metals, wood, and composites. At 120 grit, this roll falls in the fine grade range, making it well-suited for blending, deburring, and surface prep work where control and finish quality matter. It is rated to a maximum of 24,000 RPM, which is compatible with most pneumatic and electric die grinders and cartridge roll mandrels used in production and maintenance environments.

This cartridge roll is used in metalworking, fabrication, maintenance and repair, and finishing operations. It fits standard cartridge roll mandrels and is commonly used on inside diameters, grooves, slots, and curved surfaces where flat abrasives cannot reach. At 3/8 inch diameter, it is sized for small-bore and detail work. Typical users include machinists, welders, maintenance technicians, and metal finishing professionals working in both production shops and field service settings.

Installation Notes

Cartridge rolls are installed and removed by a qualified technician or machinist using a compatible mandrel sized for the roll diameter. Before mounting, confirm the tool speed does not exceed the 24,000 RPM maximum rating. Always wear appropriate eye and hand protection when operating rotary abrasive tools. Inspect the roll for damage before each use and do not use rolls that show signs of delamination or core damage.
