A needle scaler is a tool used to remove rust, mill scale, and old paint from metal surfaces.
The needle scaler has advantages over other scaling tools. Its main advantage is that the needles automatically adjust themselves to contours, making the tool a good choice for cleaning irregular surfaces. A needle scaler can clean an area to bare metal in seconds, and compares well to other scaling tools in terms of accuracy and precision.
It is recommended that before needlescaling, a surface be prepared by removing oil, grease, dirt, chemicals and water-soluble contaminants. This can be done with solvents or with a combination of detergent and fresh water.
Then, the needle scaler is used to remove rust, loose scale, and paint, leaving bare metal. It is used most effectively by holding it at a 90 angle to the work surface. It is recommended that an area no larger than six to eight inches be cleared at once. Two to three passes over an area is generally sufficient to clean it. Then the process is repeated until the desired area is completed.
