This　new non-vacuum dual-action pneumatic sander is available in three versions with different orbit diameters: 3mm (903C), 5mm (913C) and 7mm (923C). You can select the model that best suits your task, from polishing to coating application and more. The hose coupling section uses a lead-in hose mechanism that allows this tool to be moved around easily. In addition, the body’s ultra-low center of gravity ensures stability while you work.
