If you're going to go this route, probably go with this tool instead, which has a 24tpi file, and is $14:
Thread Repair File 177-1 / Pitches 11, 12, 13, 14, 16, 18, 20, 24
But really, how many times is one going to use such a tool? Add in shipping on the cheap tool and you're probably close to what it would cost to have a shop chase the threads clean and face the outer edge.
