(Also known as Pneumatic Needle Scaler / Needle Gun / Air Descaling Hammer)
Air Needle Scalers and Air Chisel Scalers are percussive pneumatic tools built to strip rust, mill scale, weld slag, paint, and hardened deposits from steel and concrete surfaces. Needle scalers drive a bundle of hardened steel needles that follow irregular contours, corners, and weld seams without gouging the base material, while chisel scalers concentrate the same percussive energy into a single interchangeable chisel for heavier removal work. ZIPP TOOL supplies medium-duty and heavy-duty models, including versions fitted with a safety lever for extended operation. Typical applications include surface preparation in shipyards, bridge and structural steel maintenance, foundry cleaning, tank and boiler work, and general industrial repair.
