The finest finish of any polisher we offer. These polishers use high-frequency vibrations to remove microscopic surface imperfections that are too small to see with the human eye. They’re ideal when you need a perfectly smooth, flawless surface in the smallest features, such as ribs and slots in molds and dies. When you adjust the stroke length, these polishers automatically adjust the vibration frequency. To reduce the risk of damaging your workpiece, they generate little heat and automatically shut off when you press too hard against your workpiece.
