The PIPE-MAX is a combination grinder and pipe belt sander. The front hard rubber contact roller drives the abrasive belt to grind flat surfaces. It removes weld seams in a straight line, without leaving edges or a wavy finish. For sanding pipes or handrails, the sanding belt follows every contour to grind and polish up to a high-gloss finish. Ideal for stainless steel, aluminum and high-quality metals.
