Replacement 2 mm needle set with holder for the Von Arx 12 B pneumatic needle scaler, an alternative to the 3 mm needles the 12 B carries as standard, for finer, more detailed cleaning. Needle scalers strip rust, dirt and weld slag, and the flexible needles follow uneven surfaces and work around projections. The 12 B itself is the smallest scaler in the range at 1.3 kg, drawing 96 L/min at up to 6 bar through a G 3/8 in connection. Von Arx 700253.
