Great! I used HF2 2 years, the tool life is incredible,and the chip evacuation. Usually I use these tools to rough closed slots in carbon steel.(HF4 needs more ramping length and careful programming ,that's why i choose HF2).After roughing ,no chip jamming on the slot wall,very clear and shining mark,it's really a nice tool!
We have some 4in long high feed mills like these at work, but the operator doesn't try to learn to use them correctly. He always makes a loud screaming trying to use it like a normal index endmill. .08 deep 20ipm= uncontrollable scream.
They even changed the old cutters with new cutters between the video shooting takes. you can see the cutter marks on the shank of the cutter and suddenly those marks disappers for the same cutter in next video shhot cut.. Lol😄
In milling with indexable end mill you often don't use coolant with plain steel (hardened steel is another case). The structure of the tool usually cools down the bits enough to not break or melt. @zaknefain100 could have explained it more but chose not to. The coolant will actually make the bits heat and cool very rapidly very often, this will wear off the bits' rigidness so that they will eventually be very brittle and break. Imagine hardening some steel to make it harder but you do it 200.000 times. It will be hard AF, but also brittle AF.

The plunge milling step-over ap and rates are what's really impressive!

Now that’s a programmer who knows how to mill 🤤🤤🤤🤤🤤🤤🤤

Crazy speed
好刀具！买买买
Come on Seco, I saw the skips in the editing in the video to make it look like it was cutting a lot faster.

it would look alot better if the camera wouldnt be wiggeling around if you dont look close enough it can look as if the tool was flexing

OH my! no coolant with such a high rate of speed!
Yes. Coolant is a good way to have one of these tools/inserts fail unexpectedly.

@@slartsa Yes, thermal shock is the nemesis of carbide.
how hard is the material
what milling machine is that?
