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.
  • Remember to consider the Torque Efficiency of your CNC machine.
  • The correct toolholder will improve production and reduce cycle time.
  • Climb Milling is recommended.

Imperial
SFM = RPM X .262 X Tool Diameter 
RPM = SFM X 3.82 ÷ Tool Diameter
IPM = RPM X IPT (CLPT) X Number of Flutes 
IPT = IPM ÷ (RPM X Number of Flutes) 
MRR = RDC X ADC X IPM (a.k.a. CIM) 
Metric
SMM = RPM X .00314 X Tool Diameter
RPM = SMM X 318.057 / Tool Diameter
