I have a production job doing 5/8-11 thread on some bolts. The 10F Landis Die Head I bought years ago is apparently so outdated that I can't get the correct holders or chasers for it, so I am back to the drawing board.

Suggestions on heads/chasers readily available to purchase to get the job done?

Edited to add: Thoughts on Geometric vs Tangential? We'll be doing about 250 bolts every couple months.

Tapping head or die head ?
Where did you inquire about Landis parts ?
 
Die Head

I checked with Small Tools, Newton Tools, Landis, ERT and searched all over Ebay. The only one that could even get the chasers and holders I need for the Landis Die Head I have gave me a $5000 quote.
 
Depending on the actual quantity and length of the bolts, this sounds like a job for a bolt & pipe threader. Just a thought.
 
Detroitautomatic. Is where I just got my inserts today, they also have heads. ( Got a great deal on a spare Geo' auto tap from them)
 
I just checked my stock on inserts, sorry no luck there, but if somebody wants some new Landis "1-1/4 head" blanks and inserts I have no use for them, 9 sets, make an offer.
 
I found a couple 1" DS heads on Ebay along with ONE set of the 5/8-11 Chasers I need. Anyone care to look at these and let me know which they'd suggest? I read in the forums that once we get over 1" the D and DS chasers aren't interchangable. I did find a 1 1/4 DS Head that I would prefer on Ebay, but no luck with chasers for that size in 5/8-11.




If anyone has a better 1" DS Geometric head they are looking to part with, let me know.
 
There are 3/4 heads in the listings....you want larger?
I was only leaning towards the 1" because the only chasers on Ebay in 5/8-11 I could find were for a 1" head. I'm willing to do any size as long as its a DS/DSA self-opening and I can get a set of chasers in 5/8-11 for it in a reasonable amount of time from Quality Chasers or somewhere. I haven't used them before so I'm not sure of the time frame they take or their pricing. I have an email into them inquiring.
 
 
Thanks! I messaged him for info.
