it is 5mm flat with 1 flute. i’va made this at 12500 rpm approx, using 1.2mm each layer during rought.
To do finishing this endmill is not good, i think will be better a ball one but right now i dont have, i will receive a complete set it the next days.
The problem will be how to change the endmill from rought to finishing…
However, this is a very bed stock, a lot of dirty while cutting
