3M 7010363861 Cartridge Roll 341D 80 Grit 0.75x2x0.25 in

Product Description

The 3M 7010363861 is an aluminum oxide cartridge roll designed for sanding, grinding, and finishing in tight, hard-to-reach areas. Built on an X-weight cloth backing with a closed-coat aluminum oxide abrasive bonded by a heat-resistant resin, this roll delivers a fast cut rate and extended service life. As the outer abrasive layer wears, the cloth backing frays to expose fresh abrasive underneath, maintaining consistent cutting action throughout the life of the roll. It measures 0.75 inches wide by 2 inches long with a 0.25-inch center hole diameter and carries an 80-grit rating for aggressive material removal.

This cartridge roll is used in metalworking applications, including work on ferrous alloys and other hard materials. It fits onto a compatible cartridge roll mandrel that mounts to a rotary tool such as a die grinder or drill. The small form factor makes it well suited for internal bores, slots, weld seams, and other confined geometry where larger abrasive products cannot reach. This product is sold in rolls; the mandrel is sold separately.

Key Features

• Closed-coat aluminum oxide abrasive provides fast cut rate and long abrasive life
• X-weight cloth backing supports heavy sanding loads while fraying progressively to expose fresh abrasive layers
• Heat-resistant resin bond maintains stability under high heat and pressure conditions
• 0.25-inch center hole fits standard cartridge roll mandrels for die grinders and drills
• 80-grit designation suited for aggressive stock removal on metalworking workpieces
• Compact 0.75 in x 2 in size accesses small, confined areas inaccessible to larger abrasives

Compatibility

Designed for use with compatible cartridge roll mandrels sized to a 0.25-inch pilot diameter, driven by rotary tools including die grinders and drills. Suitable for ferrous alloys and a broad range of metalworking and woodworking materials.

Installation Notes

Installation is performed by sliding the cartridge roll onto a matching mandrel pilot; the center hole diameter of the roll must equal the mandrel pilot diameter to ensure secure fit and safe operation. Confirm the rotary tool is powered off and unplugged before mounting or removing the roll. Follow the tool and mandrel manufacturer RPM ratings and do not exceed the rated speed for the abrasive. Eye protection and appropriate PPE should be worn during operation per applicable workplace safety standards.
