    Default 5 fLUTE 1/2-13 TAP

    Guys

    Does anyone have a source for 5 flute spiral taps - 1/2-13 and 5/8-11?

    I have a bunch of Emuge 2Enorm-Z 5 fluter 1/2-20 taps, but need 1/2-13 and 5/8-11.
    Can't find anything in the Emuge catalog, others ( OSG, Greenfield etc ) also empty.

    It is possible that the coarse pitch would leave a very weak flute so noone is making them, but checking anyway.

    Oh, the reason for the question and the 5fl is that the hole is an extruded AL with 1/3-rd of the hole missing.
    The 5fl would ensure that the "exposed" flute doesn't try to "jump" out of the hole when starting.

    Sounds like you need a thread mill...

    Kennametal makes'em.

    I'd buy em from Carbide Depot though- about 40% off MSC's prices.

    These guys make new drill bits and taps in St Paul, MN I'm not sure if they make 5 fluted ones, but give them a call.
