I meant shots of the flats, Don, with the indexed holder on its side, but that's okay, no need, I'll take your word for it. Thanks.
Here are two of my AJAX indices. One is narrower and thinner than the other. It has different markings and two internal sides with markings as well. The smaller, thicker one has no markings on its internal sides.







That's the model I just found. It holds sixty (60) drills. The markings on the outside correspond to the straight shank drill sizes, which go from 1 to (.2280) to 60 (.0400). The markings on the inside do not correspond to the drills. One is a letter size drills list and the other is a tap to drill alignment like you see on a machinists' tap and drill card or metal signage.Here are two of my AJAX indices.

I think that's the same one @Outlawmws has, but his is a Morse. EDIT: It would be interesting to compare that model AJAX of yours to his.The smaller, thicker one has no markings on its internal sides.
Thanks. My Ajax won't lay flat. I appreciate the commentary on the construction features. That's the kind of thing I was after in comparison. Also, just to see if the Morse was the same holder (1-60) as the Ajax, as I described in my post above, or not, which is why I wanted to see the outside markings. Maybe it's just easier and more effective to just write the range of the Morse out now that I think of it. Thanks, again.Lugz, I’m revising my statement from identical to very, very similar. The corner screws are different and the Morse won’t lay flat like the Ajax will.



I think you can still buy those new.Huot St. Paul Drill Index 1/16 to 1/2 by 1/64





Just checked, you are rightI think you can still buy those new.
I recently acquired the small Craftsman index shown here. Trying to do some research on its value I came across this one posted by thehorse13 and recognized it, but not as Craftsman. Mine says Ashton Machine Works, only one like it I've ever seen. I've had it for probably 25 years at least. It's made to hold taps, with the tap drills, and tap guides. I'm guessing they must have made it for Craftsman. A google search for Ashton Machine Works turns up nothing. One same as thehorse's sold on Ebay for $75, empty.After seeing all the cool ones in this thread, I'm almost ashamed to post the few that I have.
try here (google books is your friend) Pop Mech 1946-07. A google search for Ashton Machine Works turns up nothing.

Watching this as I have the same set.
Bumping this one time... ISO an "L" bit !!!Looking for an "L" bit !!! I have had this sitting around and realized I had a full set of A - Z bits. Well I thought I did!
Looks like a shop made drill index.
I would bet he was left handed as I cant looked at it and want to turn it or tilt my head to look at it.And stuck the last two off in a corner? Might hurt the OCD people... !!
Anyway, if some one has an "L" bit laying around ???
Any help is appriciated !
Go to the store and buy one.Bumping this one time... ISO an "L" bit !!!
Thanks



I believe PTD refers to Precision Twist Drill, which is a brand of Dormer Pramet.I found a couple of indices yesterday at an estate sale. The first one is a piece of rectangular plastic that originally was enclosed by a plastic box. Unfortunately, the box was broken and will be discarded but I will be keeping the plastic block. The other is an apparently unused tiny number set marked PTD. I’m not sure which manufacturer those initials refer to.
