3M 7010294687 Straight Cartridge Roll 80 Grit 1/2 in

Product Description

The 3M 7010294687 is a straight cartridge roll designed for precision grinding, deburring, and surface blending on metal and other hard materials. It uses an aluminum oxide abrasive bonded to a cloth backing, delivering consistent material removal at a medium grade (80 grit). The roll measures 0.5 inches in diameter and is rated for a maximum speed of 24,000 RPM. It is sized for use with mandrel-mounted rotary tools and die grinders, making it a practical choice for fabrication shops, maintenance technicians, and metalworking professionals who need controlled stock removal in tight or contoured areas.

This cartridge roll is suited for use in industrial and shop environments where precise finishing work is required on inside diameters, slots, grooves, and irregular surfaces. Common applications include weld blending, edge breaking, and bore finishing on ferrous and non-ferrous metals. The cloth backing provides flexibility to conform to curved surfaces without losing abrasive contact, which is particularly useful when working on inside radii or complex profiles.

Key Features

• Aluminum oxide abrasive for effective cutting on steel, cast iron, and non-ferrous metals

Compatibility

Designed as an OEM-style straight cartridge roll for use with compatible mandrels on die grinders and rotary tools that accept 0.5 inch diameter cartridge rolls.

Installation Notes

Install on an appropriate mandrel rated for the cartridge roll diameter before use and verify the tool RPM does not exceed the 24,000 RPM maximum rating of this roll. Secure the roll firmly on the mandrel per the mandrel manufacturer instructions before operating. Always wear appropriate eye protection and ensure workpieces are properly clamped before grinding. Inspect the roll for tears or unraveling before each use and discard if damaged.
