The Sandvik Coromant TCMX GC4205 indexable turning insert with WM chipbreaker has a triangle shape with a 7-degree clearance angle, providing high wear resistance for medium machining of steel in good machining conditions. This single-sided positive insert has chip grooves on one side, a countersunk hole in the center, and three cutting edges. It has a 7-degree clearance angle for light cutting forces and side clearance, making it better than a negative insert for internal turning. It can also be used when there is limited machine power, a tendency toward vibration, or when either a large or small lead angle is required. GC4205 grade is a combination of carbide and a coating of titanium carbonitride (TiCN), aluminum oxide (Al2O3) and titanium nitride (TiN) applied through medium temperature chemical vapor deposition (MTCVD), which provides hardness for high wear resistance in wet or dry machining operations. This grade also provides resistance to crater wear and plastic deformation. MTCVD coatings are deposited at lower temperatures than CVD coatings. The lower temperatures reduce cracks in the coating and provide increased toughness and smoothness without limiting wear resistance. The coating also provides shock resistance during interrupted cuts. The TCMX GC4205 has a WM chip...
