Good but not great.

Checked with my micrometer, diameter 0.778mm. Very close, but if you need a tolerance of +/- 0.001mm, look further. Good quality carbide, but accuracy could be better.

Pros
  • Price
Cons
  • disappears

Good for initial PCB drill/etch research

Inexpensive 0.8mm bits are usable but very brittle. They appear to be more useful for light engraving such as PCB etching than any type of "milling". The feed speed must be less than 200 mm/min. On printed circuit boards, 0.6 mm is only suitable for drilling.

Pros
  • Decent performance
Cons
  • Miscellaneous Miscellaneous

Not for silver? at Power Drill Parts & Accessories

Maybe they're good for circuit boards or whatever but all they've done for me is a waste of time. If you're looking to charge your jewelry with HSS bits, these bits are for you. Hand drilling didn't work so I used a drill press. Same result, the drill broke in my project.

Pros
  • Dope πŸ”₯
Cons
  • Expensive
