3M 7100188484 Rapid Removal Sanding Belt 120 Grit 3x21 in

Product Description

The 3M 7100188484 is a Rapid Removal Power Sanding Belt engineered for aggressive material removal and extended service life. Built with Precision-Shaped Grain technology, this belt cuts faster and lasts longer than conventional abrasive belts. It handles wood, plastic, and metal across all sanding stages, including coating, leveling, and stock removal. The medium grit rating of 120 makes it well suited for intermediate sanding passes where surface preparation and smoothness are both priorities. The abrasive construction resists heat buildup and moisture, reducing loading and extending usable belt life on demanding jobs.

This belt is sized at 3 inches wide by 21 inches long, fitting standard 3 x 21 bench-top and handheld power belt sanders commonly used in woodworking shops, fabrication environments, and light metalworking applications. At 120 grit, it is appropriate for intermediate stock removal on wood and plastics or light surface conditioning on metal. It is sold individually, making it practical for spot restocking on active job sites or shop floors.
