Fast, easy, economical way to reach detailed, hard-to-reach areas. Plastic stick, tapered at the end, holds a replaceable 1/4" wide sanding belt. The aluminum oxide belt is held in place by a patented spring-loaded mechanism that allows the belt to be rotated 360°. Rotating the belt exposes a new sanding surface and allows the entire belt to be used. The higher the grit, the finer the belt. Replacement belts available.
