Counterboring Titanium?

[flatgrinder]

Anyone know how to counterbore titanium for button head screws/ pivot pin?

I noticed a lot of counterbore tools say "Don't use on stainless" -isn't titanium harder to machine?

Maybe just use an end-mill?

Thanks! :thumbup:

Check out the counterbores on hawkinsknifesupply.com. i picked up one for counterboring pivots and have only used it once,but it worked great on 304ss which is tough shit.just run your mill stupid slow.i counterbore bearing races and pivots at 90 rpm i think.i'm about to try it on TI in a day or so,will report back!

I have been using cobalt endmills.

Titanium drills and mills like aluminum for the most part. Stainless steel on the other hand is very tough to machine and drill.

Commercially pure titanium is probably the easiest titanium to work with, and I'd put it along side 304 SS. 6-4 AL-V is one of the most common grades and it is like cutting prehardened P20 or 4340, except it is more flexible and conducts heat worse, meaning setup and coolant is more critical. You get to hardened 6-6-4 and you're talking about some challenging stuff. None of it is like aluminum, which is the easiest metal to work with.

Full hard 7075 aluminum is kinda like cutting steel, though it is still a pleasure to work with. The only aluminum I've ever come across that gave me any trouble was dead soft and gummy.

An endmill will work just fine.
