CoroTurn 107 Internal- and external turning with positive basic-shape insert

CoroTurn® 107 is the first choice for external and internal machining of small, long and slender components. Sharp cutting edges and excellent chip control ensure a soft cutting action and low cutting forces, providing an excellent surface finish to the component. Geometries designed for high pressure coolant is also available.
