Optimized for parting off applications, the Seco 150.10 consists of a high speed steel blade that holds the insert and a holder that retains the blade. This setup provides maximum stability, while the hot strength of the high speed steel ensures the insert will be securely retained especially when the blade is hot. 150.10 is also available in combination with Jetstream Tooling® Duo, a high pressure cooling system that provides directed coolant to the cutting edge by two streams to rake and clearance surfaces.
