Sumitomo RCMT120400ERH AC8115P – Turning Carbide Insert

The Sumitomo RCMT120400ERH turning carbide insert, grade AC8115P, excels in general machining applications on a variety of materials, thanks to its CVD coating which provides a strong balance between wear resistance and toughness. This round insert, with a 12mm inscribed circle and neutral geometry, is well-suited for turning operations that require a consistent finish and moderate cutting pressures. With its Absotech finish, the AC8115P grade is a reliable choice for CNC operators working with general materials that require a balance of speed and tool life.
