Had a shoebox of these for more than 40 years and only rarely used any of them. So rarely that I just left them behind when I retired. Now I am broken hearted. Why didn't I think of checkering?

not always , there are time u DONT want to use a regular tap as they remove TOO much metal , a prime example is the cylinder head bolt holes, most of the time u just want to clean them out,, NOT remove ANY metal,,ARP makes thread chasing "taps",they are just slightly smaller than a regular tap and remove almost no metal,,u can clean out the bolt hole AND confirm the threads are straight and good,,
I`ve had one of these for years, without the internal chasers, and it saved me when I had to clean up the threads on a faucet that had bunged-up threads where the hose screwed on. It was too big a deal to replace the faucet.
