The AIRCAT Compact Needle Scaler, No. 6390, features a heavy-duty solid steel housing. The compact, low weight design (2.9 lbs.) provides added maneuverability and precise control. Its 1-1/4” stoke and 4,800 bpm allows this tool to accomplish jobs where a full size needle scaler was previously required, the company said. The 6390 is ideal for the removal of rust, paint, and scales on flat or irregular surfaces. The tool measures 11-1/2" in length (with needles).
