3M 7010309044 Cartridge Roll P180 X-weight 3/8x1-1/2x1/8

Product Description

The 3M 7010309044 is an aluminum oxide cartridge roll built for precision grinding and finishing in tight bores, slots, and contoured surfaces. The abrasive grain is resin bonded to a durable X-weight cloth backing, giving the roll resistance to heat buildup during aggressive material removal. At 0.375 inches in diameter, 1.5 inches in length, and 0.125 inches arbor diameter, this roll is sized for small-diameter mandrel work. P180 grit provides a fine finish suitable for final blending and surface preparation before coating or inspection.

This cartridge roll is used in metal fabrication, automotive refinishing, aerospace component finishing, and general maintenance grinding applications. It is well suited for use with pneumatic or electric die grinders and mandrel-mounted setups where consistent surface contact in restricted areas is required. The X-weight cloth backing handles flexing and tension without tearing, making it effective on curved and irregular surfaces in both shop and field environments.

Key Features

• Aluminum oxide abrasive grain for consistent cut rate on ferrous and non-ferrous metals
• X-weight cloth backing resists tearing and withstands heat generated during extended grinding
• Resin bond construction provides heat resistance and longer abrasive life
• P180 grit delivers fine finishing and surface blending capability
• Compact roll dimensions suited for bore, slot, and contoured surface work
• Sold per roll; minimum order quantity is 100 rolls

Compatibility

Designed for use with standard cartridge roll mandrels accepting a 0.125-inch arbor diameter, compatible with pneumatic die grinders and electric rotary tools used in metal finishing and surface preparation applications.

Installation Notes

Installation is performed by threading the cartridge roll onto a matching mandrel and tightening according to the mandrel manufacturer's guidelines. Ensure the die grinder or rotary tool is powered off and depressurized before changing rolls. Wear appropriate eye protection and gloves during use. Operate within the maximum RPM rating of the mandrel to prevent roll failure.
