Desco Model 20 Pneumatic Needle Scaler

Light-weight, shorter, no springs, and a short stroke makes this a great value for a medium priced dust free Needle Scaler. Plenty of power to get the job done and the short 5/8” stroke controls excessive vibration. The in-line design allows the user to reach into those hard-to-get-at areas and around obstacles. Fewer needles (12) permits getting access into tight spots.
