Different types of tool holders....

[Mark P.]

I was looking through an earlier post of someone selling a Hardinge lathe. I had never seen one and it kind of rang a bell. We have had Hardinge collets in our shop forever but really no use for them. It made me think of how many different types of tool holders we have and how many were unusual?

PDQ tool holders
Anderson 300 qwik switch
30 taper
40 taper
Cat 40
Cat 45
50 taper
Weldon 50 taper (has a master that different holders bolt into)
Acroloc tooling
Browne and sharpe taper
also have a couple holders that I think were for a drill press and allowed you to change tools while the spindle was running.

I'm sure there are so many, many more than what I've seen or heard of.

My father had some for his South Bend lathe. I never saw them used. made in Los Angles I believe. the company name was Johnson or Jackson something like that. They were a tapered socket similar to a morse taper. May have had a bolt and nut down the middle to pull the taper together like a drawbar in reverse.
