Long Taps

[MikeyC]

Frogwalking,
Glad you got your taps. As others have said, Use tapping oil and take your time. Back the "Tap" out often to clear the chips and you won't have a problem. If you're not sure how often to do this, I'd do it every 1/3 to 1/2 turn. It'll slow you down, but the tap won't break. Keep the flute's clean, that's the trick.

Exactly... and don't forget to use a good cutting oil. I use Tap Magic and it's eliminated tap breakage as long as I use the proper size drill bit for the hole. http://www.tapmagic.com/
