The Astro Pneumatic AST-3039 Tube & Weld Belt Finish Sander is a precision air-powered belt file engineered for cleaning, weld preparation, and material removal on tubing and radiused work pieces. Featuring a 3/4" x 20.5" abrasive belt driven at up to 16,000 RPM, this tool delivers consistent finishing performance across curved and contoured surfaces. The adjustable roller system allows the operator to introduce slack in the belt, conforming it to the shape of round or irregular work pieces for smooth, professional results. Built for demanding shop environments, the AST-3039 operates at 90 PSI with a rear exhaust design that keeps debris away from the work area.
