3M 7100080026 Straight Cartridge Roll 80 Grit 1/4 in

Product Description

The 3M 7100080026 is an aluminum oxide straight cartridge roll designed for use with rotary die grinders and mandrel-mounted finishing tools. It carries an 80-grit medium-grade abrasive bonded to a cloth backing, delivering consistent stock removal on metal, welds, and contoured surfaces. The 0.25-inch diameter profile fits standard cartridge roll mandrels and is rated for operation up to 24,000 RPM. This roll is a common consumable for metal fabrication shops, HVAC sheet metal work, plumbing rough-in preparation, and general grinding applications requiring controlled material removal in tight or curved areas.

Straight cartridge rolls in this grit range are suited for deburring, blending, and surface conditioning on ferrous and non-ferrous metals. The cloth backing provides flexibility to conform to inside-diameter bores, tube ends, and radiused profiles. Typical install scenarios include weld seam blending on HVAC duct components, pipe end preparation before fitting, and surface cleanup on structural steel. This item is sold individually (package quantity of 1) with a minimum order quantity of 100 units.

Installation Notes

A licensed or qualified metalworker or tradesperson should install and operate cartridge rolls in accordance with the tool manufacturer guidelines and ANSI B11 abrasive safety standards. Secure the cartridge roll firmly onto the mandrel before powering the tool, and confirm the tool RPM rating does not exceed the 24,000 RPM maximum of this roll. Always wear appropriate PPE including eye protection and gloves during grinding operations. Inspect the roll before each use and discard any roll showing signs of delamination, uneven wear, or damage.
