So how do these features improve the endmill's life and ability to remove more material? Just wondering
On the KOR5 aluminum, it has 5 flutes, which translates to shallower flute gullets and thus a much beefier core. Not good for slotting as youll pack the chips into the flutes, but good for up to 40% stepovers probs. It also has the chip splitters, but they are designed in such a way that while they do chip splitting, they also leave a good finish so that you could theoretically rough and finish with the same tool (i dont usually).
Another feature of the Harvi 1 TE is the twisted face, so that the lips of each cutting edge arent in a straight line, they are curved in such a way as to provide a stronger edge. Or so says Kennametal. Someone mentioned the faceted relief which in theory reduces harmonics, and I am inclined to agree with some of the YT vidoes kennametal has posted. The thing can do full slotting at a ramp angle of 45 degrees which is ridiculous. There are flute "gashes" behind each flute which supposedly helps with chip evacuation. Again, inclined to agree.
None of these features are things that another company couldn't/isn't dong but IDK if you can buy one for this cheap.
