I have a huge lot of pipe nipple threading machine dies, geometric head dies, they are bigger than standard rigid pipe threader machine dies.
Some call them "thread chasers" I have a selection of different pitches. I probably have 400lbs all together.
minimum buy is $20 for 20 pieces. (smaller) or 10 big ones many sets of 4 could be made.
the more you buy the better the deal
good source of high speed hard steel for knife forging blanks, making lathe and milling machine tools, etc.
most are new and sharp, some are used.
most are npt, there are some bstp and fine threads as well
best I can figure out is they are M2 HSS "landis style thread chasers" for die heads
M42 is a high-speed steel containing molybdenum, chromium, vanadium, tungsten, and cobalt. It's known for its ability to maintain hardness at elevated temperatures (red hardness) and for its wear resistance. This makes it a popular choice for cutting tools that operate at high speeds and in demanding conditions
