Using these threading dies our team found that the carbon hexagon design provided precise and durable threading results. This product is definitely an asset in the industrial and scientific cutting tool market. The compact size and portability of the dies added convenience to our workplace operations. The only downside was the initial investment needed, but the long-term durability makes it worth it. .
Pros
Efficiently rethreads damaged or stripped threads on bolts and nuts.
Cons
Requires some level of experience and skill to use effectively.
To my surprise, I was able to successfully thread a stainless bar with this die! All I had to do was cut some rods (about 3/8" thread length) and he did. I can't comment on its durability or stainless steel type/hardness.
