Some great advice for beginners, well done. It would also be good to highlight when you should not use each end mill. Using the right machinery for a job is crucial to the quality produced.

Would love to see a video discussing various coatings and when to use certain coatings, what material they should be used on, with or without coolant etc. Been in the job a while but I'm eager to learn new stuff!

I wish he would have covered when NOT to use each. 5 flute will not do well plunging or when there isn't a lot of room for chip evacuation. 1 flute will not leave a good side finish unless you feed really slow. Someone with little experience could come away from this thinking they can all do it all well.

The 3 flute is my go to end mill for a lot of stuff.

Best # of flutes is totally dependent on the cutting application. In high speed machines, making a 2-flute work can be difficult due to cutting harmonics and natural frequencies of machine tools. I have 2 large high speed gantry mills (20k rpm) in my shop and they are very sensitive in this regard. Also, wall thickness calls for a specific flute count such that 2 flutes can maintain contact, which helps stabilize harmonics in thin walls at high aspect ratios. If everything could be machined as quickly as possible with trochoidal type toolpaths, you could probably make a case for a set number of flutes as 'best case' but that simply isn't the quickest way to process everything.

Overall a good intro video though.

I learned sign language today from you

I watched this. Then read all the comments. Then went to another video. Then remembered that I did not thumb up this video. Came back to "like". Only Titan gets that dedication from me. lol

[gregmarshall]

I love how "grown up" these comments are! I was trying to listen but all I could think about was Ricky Bobby not knowing what to do with his hands!

[NORTHBROOK]

I run plastics.. and those one flute bits work great.

[justinbrennan]

Thanks for the knowledge!!! You guys are changing the game!!!

[wayneshephard]

Awesome info, thanks for sharing your knowledge

[pqfgpqq]

could you do an overview on a models for steel and cast iron roughing machines? where there are reliable guides, spindle etc.

[tomhutchins]

My experience more flutes the better for finish and especially wear. As long as you can get the chips out and cool. Hangstefers used in a Flood system makes a huge difference. also in theory if you have to spin 7000 rpm with a 2 flute a 4 flute only needs 3500 rpm and is much less chatter prone. I have a 6500 lb acroloc m12 so its heavy but only fairly ridged.
I have tried 3 flutes and the tool wear was poor . 2 futes are really vibration prone and dont last long .

[aaronw]

I can't remember what brand of CNC machine you are using. Please make your videos longer so that we can make sure more people know what brand of machine you endorse.

[MrBrettStar]

What finishing pass thickness is usually required for radial and axial passes?

[danl.]

In other words, for aluminium use how many flutes as you want as long as it is not 4 flutes. Did I get it right?

[jasonstatement]

Pay attention to your posture my man! You're still young, plenty of time to fix it. Info was great btw, keep it up!

[kabadaluk]

3 flute is the best option for almost all types of cut.

[Lucas_sGarage]

im gona use thin info on my 3018 pro lmao wish me luck

[manfredweberhofer]

Can you make a video about how to start your own company in the garage? I mean you won't be able to machine a lot of parts with a single cnc mill in your garage. Should I ask smaller company's to produce parts for them or just private people or car shops etc?
