    Default Looking for a 7 pitch acme internal laydown threading insert.

    Does anyone know who makes a 7 pitch acme laydown carbide insert for internal threading. Everyone I checked makes 6 acme and then jumps to 8 acme.

    I can only find 7 pitch stub acme, and those are solid carbides, not inserts.

    now, my gray matter isn't working very well today, but if this is a stub form I think you could use a 8tpi insert and grind off the end to suit.

    Vardex does, but you may need their holders.
