What's the life time for our threading dies?

According to our test on 2” galvanized pipes, the Alloy threading dies can make around 300-400 threads, the HSS threading dies can make 800-1200 threads. 

Please be noted, different types of threading dies has different performance, the pipe size and material can also affect the dies life time directly.

We hongli are keeping developing new threading dies with different material and tech.
