Helix Angles: In The Loupe TV Ep.4

While many factors impact the outcome of a machining operation, one often overlooked factor is the cutting tool’s helix angle. The Helix angle of a tool is measured by the angle formed between the centerline of the tool and a straight line tangent along the cutting edge. Join the Cutting Tool Counselor, Don Grandt in episode 4 of In The Loupe TV to learn about helix angles!

excellent video!

[@kleindavid9416]

dude knows what he is talking about (refreshing...)

[@danielmschell]

Honestly so grateful you guys are talking about things that are 100% relevant to me.

[@dongrandt372]

Thanks for watching.. Stay tuned for some more great content.

[@craigm712]

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.

We are trying to do our part to teach a person to fish vs giving out Fish! LOL

[@muralinaik6511]

Don, Thankful for u for such wonderful sessions.. Often re visiting your videos to refresh my understanding about the cutting tools.. Thanks a ton!!

[@daffyf6829]

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.

[@dongrandt372]

Anything to help understand it better.

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

[@CuttingtoolCounselor]

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

I mean Don.

Thank you !! Sub + Like + Comment

what about 37 deg "variable" helix? I hear that's a good choice for trochoidal style cut

[@dongrandt372]

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.

[@CuttingtoolCounselor]

Hard milling is coming up... Thanks for watching. Ctc

Good video and info but could have been half as long.
