Many moons ago when I was a travelling wrench I always used Craftsman taps largely because when you were in bumblefuck USA you used to always be able to find a SEARS. I once won a $100 bet by tapping over 100 M4 blind holes using a drill without breaking a tap.Wouldn't you know it, Project Farm released their tap n die test yesterday. Irwin and Craftsman came out on top.
