3M 7100080018 Cartridge Roll 40 Grit 0.25x1x0.125 Inches

Product Description

The 3M 7100080018 is an aluminum oxide abrasive cartridge roll built for aggressive material removal in tight and contoured areas. Constructed on an X-weight cloth backing, it delivers the durability needed for high-pressure grinding and blending applications. The resin bond system resists heat buildup during extended use, helping maintain cutting performance and extending roll life. At 0.25 inches diameter by 1 inch length with a 0.125-inch arbor hole, this roll fits standard mandrels used in die grinders and rotary tools. The 40-grit designation makes it suited for rapid stock removal on metal and similar hard materials.

This cartridge roll is used in metal fabrication, welding cleanup, and surface preparation work where a spindle-mounted abrasive is needed to reach bores, slots, tubes, and irregular contours. The X-weight backing withstands the lateral and rotational stresses common in die grinder applications. It is appropriate for use on ferrous metals and is commonly used by machinists, fabricators, and maintenance technicians working on finishing and deburring operations in industrial and shop environments.

Installation Notes

Installation is performed by threading the cartridge roll onto a matching mandrel before securing it in a die grinder or rotary tool chuck. Always confirm the tool RPM rating meets or exceeds the roll's rated speed before operation. Wear appropriate eye and face protection and secure the workpiece before grinding. Inspect the roll for tears or unraveling before each use and replace if damaged.
