Metric die for optics

might try Grand Tool Supply Corp. they are in NJ and typically have good Metric from Europe. They have been responsive to me in the past.

I can understand that. These are rather fine threads, certainly not standards. Even 6mm has a 1mm pitch, so these should be quite a bit larger pitch -- if they weren't optical threads.

Frankly, I would consider the ideal die for this purpose to be a lathe with metric single-point threading capability. Dies with that fine a pitch will be difficult to start straight without the assistance of a lathe, anyway.

Good Luck, DoN.

I'll give Grand Tool Supply Corp a try on monday.

Thanks for the help.

I would only use the die for touch up work for damaged threads only.

Thanks for your help.

O.K. But I suspect that you won't find them as standard parts, anyway. You could go through one of the big tool catalog companies, like MCS, and they can find a company who will make it for you. I had to do this with some special threading chasers for a Geometric die head a while back, and MSC was quite helpful about it.

But these *will* be significantly more expensive than standard ones.

Good Luck, DoN.

I'll give MSC a call next week and see what they can do for me.

Thanks, Jack
