The HARVI 1 TE is a complete Beast in Steels, Titanium and Super Alloys. I have never seen a tool come close to the MRR that this thing puts out while full slotting 3XD and Ramping at 45 Degrees etc. Remember, machining is all about productivity and efficiency... Therefore having standard tools is incredibly important. Instead of purchasing a ton of different types of tools for Milling... I simply use HARVI 3 for profiling, trochoidal etc... Full Z Depth with 10-20% Radial. Then I use HARVI 1 TE
