The Dynafile abrasive belt machine grinds, deburrs, blends, and finishes normally inaccessible areas on metal, plastic, fiberglass and other composites. Light corner weld removal and the blending of welds are typical applications of this tool, but the patented abrasive belt tracking system provides trouble-free operation. Over thirty different interchangeable contact arms are available for a wide range of applications. The Dynafile uses coated abrasive belts ½”, ¼”, or 1/8,”wide x 24” long. Non-woven Nylon and Cloth Polishing Belts are also available. The 20,000 RPM tool weighs only 3 lbs. and the lightweight, composite housing reduces vibration and is thermal insulated to prevent cold air transmission to the operator’s hands. The air motor is also adjustable to the most comfortable throttle lever position.
