Fuji needle scalers are useful for removing weld flux, sand from castings, scales from forgings, rust, paint, scales from ship hulls and finishing rough surfaces of rock or concrete. Fuji needle scalers feature a unique valve less design and work well on uneven or irregular surfaces.Low air consumption 0.14-0.18 m3/min (due to the valve mechanism) enables Fuji chipping and calking hammers to be used with a smaller compressor. The locking handle are designed to reduce the risk of accidental starting of the tools. The handle is automatically locked when the operator releases the handle.
