You guys are doing a great job on the format. Keep the tech info coming, please! I wish more manufacturers understood their customer base as well as you guys.
I had a huge 3 1/4 cl 4flute helix as my finisher . Squeeling like crazy!! Huge helix on it. Went to a more gradual and had nothing but rigidity and finish
High helix will also put more tool pressure and points of contact. Certain materials require a more strategic approach. By going 3.250 deep with a high helix just created too much! Thanks for the comment and watching.ctc
Anything that is Variable, like Pitch or Helix will always produce a smoother finish and create less chatter. 37 Degree Variable Helix is a winner if used correctly.
I Never Ever Take Spring Passes. It Dulls the End Mill. I Machine a Lot of Heat treated D-2 60-62 RC. After 1 pass my E.M. is shot. My Tolerance is + or - .001. I go for broke right off the bat. If i do have to take .001 off, I have to Comp out .005 just to take .001. It's Scary. I have the same problem with surface grinding. Sometimes I machine CPM 10 V. You want to talk about a guarantee bad day at work. I hope Dave goes over Hard Milling.

We are trying to do our part to teach a person to fish vs giving out Fish! LOL
Don,
Thankful for u for such wonderful sessions..
Often re visiting your videos to refresh my understanding about the cutting tools..
Thanks a ton!!
Thanks for the info! It's one of those topics we machinists don't put into words, yet somehow seem to expect everyone to know haha.
Anything to help understand it better.
excellent video!

Hi sir
It's a nice information thank you
Please share some information about multiple helix angle endmills
what about 37 deg "variable" helix? I hear that's a good choice for trochoidal style cut
