Re: [CAD_CAM_EDM_DRO] Re: Thread milling!!

Jon,

Who was your source for that cutter, and what pitch range does it have?
The one MSC sells for a 5/8 thread is .500 in dia.
One of the attractive things about a lathe threading bar is that inserts
are available in a range of pitches. But it would only take 3-4 of the
single row type to cover most threads anyway.
For the job at hand, if it went into production as designed, I'd surely
buy the full thread type and spin the thread in one pass. With a
potential for hundreds of holes threaded, the time savings would cover
buying a dedicated pitch cutter.
If the job doesn't go through, I'll just start laying in a collection of
the single row type.
