Kennametal CCMT3251FP KCU25 – Turning Carbide Insert

The Kennametal CCMT3251FP turning carbide insert excels in finish machining applications on steel workpieces, where its KCU25 grade and TiN coating provide excellent wear resistance and enable smooth, accurate cuts. This diamond-shaped insert, with an 80° rhombic geometry, is well-suited for neutral machining conditions, allowing for precise control over the cutting edge and minimizing the risk of deformation or vibration. The TiN coating on this insert helps to reduce friction and prevent built-up edge, making it an ideal choice for achieving high surface finishes on steel components.
