Endmill Fundamentals

I’m new at this milling work, and this is very much knowledgeable for me to learn, thank you for this informative experience..

Before matriculating university, I spent over 20 years in tool rooms mold rooms and tool and die Never saw a carbide end mill. HSS is perfectly fine for all alloys of steel just not pre-hardened. If there is a down side to it, it is that you have to go slower and pay more attention to coolant. In fact on mills such as the one you have there Carbide is probably the wrong choice almost all the time because your bearings are old and small and worn and not rigid enough to provide the ridigity carbide needs. So you are probably getting half the expected life of a carbide end mill.

Very descriptive and clear explanation. Thank You!

The explanation of climb cutting vs. conventional cutting was very good. The explanation of how to do the finish cuts was incomprehensible.

Very good! simple & clear.

G'day and greetings from Tasmania Australia 🇦🇺 your explanation of what you were doing and the difference between the the different cutting techniques I now know what was happening as my cuts weren't very good. I have subscribed and look forward to watching your channel again thank you very much, John

Fkng outstanding! Thank you so much for these tutorials!🙏👍👍👍👍👍

Very informative, thank you !

Thanks for sharing this very useful information.

Thanks for your Knowledge , very helpful for a newbe.

I climb cut the final .010 or so. Chip load is small, finish is better. But never for roughing!

Interesting and informative. Thanks.

Imagine if we could cut steel with hss. But I guess that is simply not possible

Thanks for making these videos, I am sort of stuck at a job where we do make some custom parts and the lead machine shop guy quit and left me to figure it out.

Dude this video is perfect.

Thank you so much it makes sense

Thank you from a newbie!

Great job on the video

I’ve been using high-speed steel and mills on Steel for 40 years. You just need to get your speed and depth of cut correct. A little cutting oil won’t hurt. Of the three carbide end Mills, I think you chose the wrong one. I would’ve gone with the larger one. The larger end mill would have been more rigid and all-around more useful if you were only going to buy one.

THANK YOU !
