    source for these toolholders (US Patent 4,902,177)

    I have some toolholders that are stamped "Light Machines US Patent 4,902,177"

    The patent is here: https://patentimages.storage.googlea.../US4902177.pdf

    Figures 7 and 8 exactly match what I have.

    Light Machines was a 1990s vendor of CNC mills for the educational/vocational training market based in New Hampshire.

    It's possible they bought the exclusive patent rights or alternatively that they just licensed them.

    I'd like to pick up some more holders, curious if anyone has ever seen this style of tool holder produced by any other companies?

    That is a very nifty system. Looks like an ERxx collet without the saw cuts. Should be simple enough to make?
