Purchased Irwin Hanson tap and die…
Purchased Irwin Hanson tap and die combination set. Some of the taps and dies are the wrong pitch!! I tapped a UNC 7/8 -9 hole and threaded a bar using the 7/8-9 die so they would fit into each other. However it would lock up after 3-4 threads. Upon further inspection the die is cutting around a 9.4 tpi thread 🙄. Now what really annoys me is when you try to contact the company but cannot find any contact details. No email, no phone number so I’m left to come here and see if I get it sorted. Not really impressed and this set was not cheap. Im going to park the set to one side as im afraid other pitches will be incorrect.
