Helical High Feed Endmills for Aluminum

High feed (bottom cutting) end mills need 5 to 10 times the normal feed to work right.
This is due to the chip thinning under.
In aluminum this puts you at speeds very few machine tools in the world can do.
Side cutting is not done with this style tool. You will kill the end of it or the side.
Understand and look at the cutting action taking place.
People talk truth and you will see it works and it fails.
