I don't have any Wright tools, but I just posted this in the giant breaker bar, or similar, thread, as we are going thru an ordeal at work. This is for large hex impact bits, 1/2" and up hex size. YMMV, etc; but we are not hardness file testing- we have real test equipment.
We also found that Wright impact bit sockets are superior to Proto- we tested those also, including the RC hardness.
