PYTHON: 45 Degree Helix – Primarily for general purpose versatile machining of non ferrous and steel.
Since not every company has the RPM or need for high Metal Removal Rates (MRR) the Python is a great choice for general purpose machining, and it can both rough and finish. It's designed for slotting and heavy profiling. The “General Operating Range” is based upon 1X diameter (ADC / DOC) in full diameter (RDC / WOC) SLOTTING. The minimum chip loads remain constant for all applications, however, the maximum chip loads can be increased for side milling applications in finishing, heavy roughing & light roughing.
