Very good and clear tutorial video demonstrating the best 2 ways to mill professional T-slots. Thanks it was a great help and nicely done 👍 The slower rotation speed and slower feed speed works very well to prevent your milling cutters from damage and overheating.

It’s true that this could have been done faster but this machine doesn’t look super rigid. You have to work with what you’ve got so I give you kudos for that.

First let me say thanks for all the great videos! I really like them and regularly recommend your channel because it's just great and different. In a positive way! Now to the criticism: If it slipped in an ER25 collet it's 100% an operator error or the holder, nut and collet are the worst junk possible. ER25 should have a slip torque of at least 50Nm with larger shanks, if not quite a lot more. I know ER32 has above 110Nm with a 13mm shank, not properly cleaned. I've seen spindle load meters pushed into the red part with just properly used ER25 on way, way stronger machines. They can take more than many small VMCs can dish out. Was everything (holder, nut and collet) of good brand & quality? Was it properly cleaned & maintained? They shouldn't be lubed, rather degreased before use. Did you torque it with the recommended torque for ER25 with tools 8-16mm of roughly 100Nm? Many people way underestimate the needed torque and way overestimate the torque they can bring up with a tiny spanner with sharp edges. To make it short - the ER holder can do that easily without batting an eye! I have no doubt about that. But with collet chucks operator error is extremely common, even amongst professionals. In the end what matters is that it worked out. But I had to mention it so you have a chance to improve your practices. Keep up the great work and thanks again for all the time I could spend "with you" during quarantine! Grüße aus Hamburg! (Keine Ahnung warum ich's auf englisch geschrieben hab...)

Thank you very much. The manufacturer of the mill is a small German factory in Birkenau named Prechtl. It is mainly a factory for exclusive and fine guns. The brand for the mills is GOLmatic.

Why in this process he didn't use coolant?

Afaik carbide/hard metal doesn't like temperature swings because it may break, so it's either perfect flood cooling (ideal) or no cooling at all (runs hot but at least the temperature doesn't fluctuate).

He also used speeds and feeds that suit high speed steel. 5x the rpm, 10x the feed would be my first adjustment and then see how it works. Coolant isn't necessary and makes a huge mess
