That’s very very nice!
Just a reminder - Keep in mind that if you decide to use any filled filaments like CF, Wood, some Marble, etc the .6 nozzle is recommended to prevent clogs.
A CHT doesn’t help as it still has a .4 to squeeze through, besides you can now change nozzles easily! 
Cheers!
Pay attention to your temps for the filament and layer adhesion. Too hot and you change the properties of the filament.
Sorry. My browser did not load the whole page ^^ Deleted my post xD
Well so I remove mine too for a better reading, I have also added a shortcut to the first post of this thread to avoid confusion.
0.4nozzle @240C, Line width/Layer height 0.6/0.2 mm, vase mode, real volume rate 42 mm3/s
Adhesion is pretty good:
I gotta get me a cht nozzle
Printing flawlessly at 400mm/s, 0,4mm nozzle, 0.2 layer height.
Thank you for the thread.
The CHT clone is a rocket 
I don’t know if Bondtech added this recently; their CHT MOS Brass M6 nozzles lists “Bambulab X1 (aftermarket hotend)” as compatible. No change to their Bimetal hotend description though. The nozzle geometry differs but I think they are both the same height.
This looks like it will flow faster than cht clone. Why is it anyone selling a ready made kit for this? Im not a maker just a printer. Hacking is not my thing, I cant even understand how to hook this up.
Thanks for this info. As of now there is no .6 hardened steel high flow nozzles right?
after few second of joyce, It seems to be the same as before, still a bit too long, anyway it works but it is not optimal for the Bambulab IMO
Coated nozzles are a lot more resistant than standard nozzles but not as hardened nozzles
Thank you for quick reply. Hopefully there will be a proper length solution eventually.
Yes, I saw that too @mol.olsson when looking for a hardened CHT nozzle, but was unsure of length so held back. Thanks for the update on length @s.3, and my aftermarket clone has just landed via AliExpress this morning. I might try and pull out the copper core from the brass nozzles I got too, and see if I can use a carbide drill and fit the copper core in the hardened one.
Hmmm, need to make a small tool to remove the copper insert. 
Looks doable

For my understanding… copper is softer than brass. Does this copper core not wear out too fast?
No, the nozzle does not wear out (any meaningful amount) on the inside, it does wear out on the tip of the nozzle and slowly gets grinded off. Hardened materials can slow down that process by a lot, but will wear out eventually too.
Is there a model of the heat block and cht nozzle that is the same length as the original and the printer won’t give error?
Thanks,
Can’t i just buy the combo from the first store linked?

yes this link is ok.
