does anybody know or sell or know where i can a tap and die for tapping and threading titanium? i just bought some 5mm titanium rod and now have broken 3 dies trying to thread it. one of the dies was a hanson and the other 2 were snap on. i just want to make my own links instead of buying lundsford at $10.00 to $15.00 each and then have to wait for them. any help would be greatly appreciated and fantastic.

threading titanium rod

has to be turned down to the correct major diameter, if you are trying to die 4mm it should be
from 3.83 to 3.97mm
the easy to remember cheat formula for cut tapping metric is to subtract the pitch from the major and that your drill size.
so a 4.0 x .7 thread is 4.0 -.7 = 3.3 mm drill size

I was told turn down where your threading to 3.65mm for best results. That's what I'll be doing on mine.

So how did it work out?
I tried to die 4mm titanium rod yesterday with a normal HSS die and it was a pain. A lot of noise and smoke but little thread. :ror:
I'll give it a second try today with proper tapping paste and a cobalt die.

Thanks for the information, Egressor.
I was recommended a cutting paste by a local shop specialized in product for metal work. It's more like a wax that I apply with a brush. Maybe something more towards liquid-form would work better?
But I got it working using cheapo HSS dies. I noticed it is a lot about technique. First I used a power drill but that didn't work for me. It does work well with stainless, though. Titanium is so hard that you have to go slower and doing the thread by hand gave a much better result.

it´s the low thermal conductivity + the high tensile strength what makes it hard to machine
i like the cutting fluid more than the paste , works better for me

Nobody has said anything about the right tool for the job.
The round die is for threading and the die nut with hex sides are used for cleaning/chasing threads.
If this is for links ?
I drill a hole and run a tap into the hole. Then use a set screw for the threads.
Make it easy on your self

Your boring ti solid rod? What bit are you using to drill with?

Hi Erin
I use a lathe. HHS drill bit. Its really not hard to do. What Ti rod are you using and where did you get it. It should not be that hard. Tell me how you do it.
PM me I will help you all I can.
Evan
are you using the softer Grade 2 or the 6AL-4V grade 5 titanium?

I use ti 6-4. I have never used the softer alloy. The grade 5 that I use is only HRC36. HRC36 is hard but slow moving hhs ( high speed steel is HRC60 ) is not a problem.
I dont use Ti very often. The need never exceeded the cost. For links i use are made of tool steel T1 (oil hardened ). T1 has a hardness 35HRC, but I can change that hardness from softer to harder with just a torch and oil. The oil used for heat treating. The reason for special oil. (????) For Ti I need a vacuum chamber.

so its more to do with the feed rates and coolant, then the bit used. Makes sense.
I haven't tried it yet, but I know others have had trouble drilling and turning it.
