    HSS pot scrubbers - for when you absolutely, positively have to ruin your old ladies non stick pans. It probably would polish up hardened drill rod/O2/A2 very well.
  • @Rustinox
    Turning cobalt HSS as if it was aluminium. That's quite spectacular.
  • @624Dudley
    Nice compilation from the live version! 👍 The slo-mo really reinforces the way the chips take out the heat. Looking forward to the broaching process, too.
  • @TheChillieboo
    That’s amazing watching those chips glow! Thanks for this sweet video
  • @gioben5444
    You should add a time delay on the spindle.0.at-speed pin in the LinuxCNC to prevent cutting before the spindle is fully up to speed.

    Hi Mark that sure does glow pretty. I did forget to mention on our live stream thread about the taper, is that you can program it out. Once you know what the taper is you "simply" program that as your tool path. It's done all of the time in production, especially for parts turned between centers , there is no way around part deflection otherwise.
  • That was really cool, it's truly amazing the advancements in tooling these days. 👍

    I'm a hobby machinist and have spent 30 years trying to learn as much as possible. This video was the best, most engaging learning I've experienced since hanging out with my 90 year old tool maker friend when I first fell in love with machining. THANKYOU for your time and content. This was so good. I fully thought you were kiwi like me with your accent, but maybe an Xpat... thanks from down under down under. Chch nZ ❤
  • @mumblbeebee6546
    Spectacular shots of the chips, and real interesting video!
  • Making glowing worms like that, you should be wearing a wizards hat.
  • @tinygriffy
    First seen on the Internet .. Phase Change Inserts .. really nice shots.. thanks !!
  • @SuperAnodyne
    Wow, great videography! Really liked the close up Makro shots. As for the chipped insert, you at least can touch them up one time, just put on a nice slightly negative radius on the cutting edge.
  • @chopper3lw
    Wholly chit! those red hot chips are insane, but look at that finish!
  • @LongnoseRob
    Impressive to see the redglowing string of chips! Looks like the insert would love to see even more speed
  • it's really cool to see someone actually hard turn on youtube. hopefully we can see more hard turning with say something like 4140 ph
  • @kuglepen64
    Those macro shots! That surface quality! Yowza.
  • @holinkavladimir
    Oh man, that fiery lava swarf is just music to your eyes...
  • @r0311
    That's so cool when the metal gets separated and starts glowing. Don't touch 😁
