Unique hole saw for metal cutting Special trepanning tool

1. ■Cutting condition
   Vc = 80 m/min
   fz = 0.08 mm/rev

   ■Work material : SCM440

2. As a mechanical eng, videos from this channels soothes my brain

3. Looks like its cutting backwards and the wrench looks like its tightening nothing but an empty hole.

4. What is the accuracy?

5. Is this essentially an indexable annular cutter?

6. PERFECT

7. MARAVILHA 🤩👍🏿

8. Tungaloy are so innovativ and experimental! 🙌🏻

9. Awesome 😂

10. Trepaining tools are absolutely awesome the only issue, is they're great with plates on a vertical mill where th3 puck can be ejected, great jobbing tool, not to nice in a manufacturing and mass production setting, a really cool and awesome tool though, a form of ejection, and way of drawing the puck away in lathe operation or horizontal milling would be awesome. Sure tungaloy isn't far off from something like that, they are top of the line.

11. Even leaves some useful scrap discs, instead of a load of swarf

12. Can this be used for plunge milling strategy? This tool would greatly increase material removal rate if you factor in the central core that is removed in one piece.

13. Why haven't I seen this before?

14. where to buy?

15. What diameters are avaliable?
