Product overview
VonArx pneumatic needle scalers remove rust, paint, weld slag and other deposits from uneven and profiled surfaces using a bundle of flexible needles. The needles adapt to contours and projections, making these tools suitable for surface preparation in industrial maintenance, shipyards and fabrication shops. Models are available for different needle counts and needle diameters (2, 3 or 4 mm).
