I found a box full of geometric die head chasers
How do I tell what die head they go to?

When I was 'between jobs' in the past, I sharpened a few Geometric die sets , but never had a head to work with.

The size of the die head is marked on the box that the die set comes in.
The Newman tool list above is only of the die head sizes, and not the die sets themselves
If you have no individual boxes , then you will need to measure a die and post the dims here.
I have 3 Geometric heads (5/16, 9/16, and 3/4) and the dies are all different .

Ok then try these folks:

Note that the Geometric business is now owned by Landis Threading Systems, so try here:

There used to be a Teledyne-Landis that bought out Teledyne-Oster, the threading equipment company I used to work for. Landis Threading may be the offshoot of T-L, but who knows, these days. Oster threading equipment is now made by Superior Threading in Owasso, MI. Superior is owned by a former T-O sales manager. One needs a score-card to keep up.

Some of the chasers I have, have the head size marked on them. Clean up a few and look closely.

This thread got me to thinking about my Rickert- Shafer automatic die head. It is very old yet in good shape. The chasers are of a style as another manufacturer, Modern Machine. So I was looking past those while not knowing that Modern bought R-S around 1975 .

Recently seen are numerous Rickert Shafer heads and chasers. Most are sold now. I quit looking and missed that window. This gets back to a particularly nice shaped handle which has been replaced by a bolt and sleeve.
Many thought these old heads were shot and over because there were no other chasers. They are there but reasonable expensive. Probably tons of them went to scrap or went to other purposes because we didn't have the "net" then. 1911 patent to even 1998 is a stretch (except for other tools) so many are lost. I digress. The handle of them is a work of art. It is a finial of first order AND that is why we can see these heads anew with bolts instead of the originals.
