Die Set, M6 - M20 Rethreading, Hexagonal

The hex-shaped bodies are a lifesaver when you need a wrench on a stubborn bolt instead of wrestling a round die. I cleared up a rusty M10 thread on an old trailer hitch in about ten minutes, and the M6 through M20 range covers every common size I own. Slick little kit.

Finally got to use this die set on a rusty M12 bolt, and it cut clean threads without binding. Having the full range from M6 up to M20 in one case is incredibly handy for general shop work.

The M14 die went through a corroded bolt surprisingly smoothly after a bit of oil. Nice to have the M20 included even if I don't use it often. Only thing is the case could be sturdier for the price.
