    shrader Thread tool

    Hi everyone I'm searching for thread tool for shrader valve (inner thread). I'm not familliar with this sort of things. I just know some dimensions like those from wikipedia:
    Internal thread (to accept the threaded valve core)
    Metric: 5.30 mm OD 0.706 mm pitch
    Imperial: 0.209 in OD 36 tpi.
    But I'm from poland so it's hard to find threading tool not metric standards.
    So if you know that kind of tool send me link to it so i maybe know what to search for

    Are you just chasing the threads, or cutting new ones for a custom application? Here in the US you can go to any auto parts store and buy a Schrader valve tool.

    Example:

    • Imperial: 0.305 in OD, thread root diameter 0.271 in 32 tpi (threads per inch)

    Internal thread (to accept the threaded valve core)
    • Metric: 5.30 mm OD 0.706 mm pitch
    • Imperial: 0.209 in OD 36 tpi.
