Only used it once to tap a 7/16 x 16 hole, and 4- #8x32 holes in 1/2" mild steel plate. A large tap should not be a problem, small holes, more so. Not with this set. I never felt the tap would break and it produced a sharp thread profile. Go slow and use plenty of cutting oil. This set will last me my lifetime for my johnny homeowner shop. The ratcheting die holder is a nice touch as well as offering two collet type tap holders - much better than the T handle type that always seems to loosen at the wrong time. I would buy this again.

Decent sets for the money, worked well but probably won’t stand the test of time.
