Product Introduction:

CNC lathes are the most widely used machines and an insert geometry that enables both external turning and facing is the most common choice. 80° rhombic inserts are suitable for both roughing and finishing of faces and external diameters. Square inserts (negative) can use both sides of the insert. Therefore the number of corners is doubled, offering the user lower cost. However they can not be used for both external and facing operations. Under the same machining condition, the maximum overhang of cemented carbide tool holder can reach L≤6D, while the recommended maximum overhang of steel tool holder is L≤3D.
