You are absolutely right. I spent the better part of my career in the tool supply business along with my machine shop. I chose not to challenge the other presentation on it. I have both re-threading taps and dies and tread cutting taps and dies. Re-threading dies are hex, that is true. I sold Vermont American taps and dies, their threading dies were hex, I also have Craftsman hex threading dies.
But I want to know if you can cut with a rethreading die? I need a 7/8" - 32 die for threading mild steel. For some stupid reason, my chinese lathe doesn't have a 32 pitch option. It skips from 28 to 38. WTF!? I don't want to spend $70 for a cutting die and rethreading dies are much cheaper.
It may or may not work. I suggest searching ebay for an actual cutting die. Sometimes you can find a new old stock one for your needs. Or hit social media and ask around in hobby groups. You may find a solution there. Hope this helps.
What irks me is the outfits that sell a chasing set as a cutting set. Usually cheap chinesium sets sold at automotive chain stores or even at the chain harm & fome stores.
I cut 1/4" -28 brass rod with an octagonal cutting die for a tapped brass hole expecting a snug fit, but the fit is rather loose. Is this standard or the result of a cheap Chinese die?
I use almost exclusively hex dies, the ones I use are not retreading dies! Yes, retreading dies are hex dies, but hex dies can be thread cutting type also as James states! I like the hex dies especially in the larger sizes because I can use a wrench on them.
Very good explanation, I learned something new today. One problem I constantly have is drilling a blind hole too shallow. Maybe you can do a quicky on determining how deep a blind hole should be drilled to have room for a taper tap, plug tap etc, and still get enough depth for the intended bolt. Thank you.
Pat Wicker measuring the tap and adding 25% of the threaded length of the tap to the total depth of the hole is what I was taught inorder to have enough threads after a finish run with a bottom tap.

Are rethreading dies only good for one use or how long do they usually last?
Depending upon how tough the material is that they are cutting determines how long they last.
@@eagledustoff37shortserious65 ok thank you for the quick response loved your video
Smart man
Thank you.

Perhaps or end up destroying the die or the material itself.

He was always talking about facebook, which I don't do. If you do, look him up and see if he's still on there and let us know.
How long will he be gone this time?
The lead in helps to center and start your threads straight! James, this is great video on this subject. See you on the weekend!
