An Industrial Vertical Air Grinder is a heavy-duty pneumatic grinding tool designed for rough grinding, surface preparation, weld seam cleaning, and material removal on large metal or stone surfaces. Unlike straight or angle grinders, the grinding wheel is positioned vertically relative to the tool’s motor, allowing the operator to apply force directly downward — ideal for flat or horizontal work surfaces such as ship decks, steel plates, or foundry castings. Powered by compressed air, this grinder offers high torque, continuous operation, and excellent cooling, making it a preferred choice for shipbuilding, fabrication yards, foundries, and heavy manufacturing industries.
