Good to see you getting a collection going.
I bought my tool post pre internet days and had a lot of money in it which I wouldn't get back if I sold it, thats the only reason I made mine. If I was starting now I would be buying through CDCO at $9 each.

Hi Dave,
You can never have too many tool holders. CDCO claims they are hardened but I can deburr them fairly easily with a file. I might try machining the area where the tool sits with a carbide end mill just to get a good surface for the tool to sit on.

I cannot comment on the CDCO tool holders but the ones I have from tools4cheap are machined well and nicely finished. The set screws are not very good and I just purchased a box of 100 to replace them. I will be ordering some more from Jeff soon.

I took the time to clean up the six tool holders today. They needed deburring, as usual, and all six of the thumb nuts wobbled as did three of the regular nuts. So out of the six I bought all are unusable until I replace the bad parts. Definitely time to try some of the tools4cheap version.

Ed, I think those studs are the infamous 10mm fine thread "setscrews" that are hard to find, I imagine, the nuts would be too.
I still use mine, if you lock the nuts up tight to the knurled adjusting nuts they hold ok, but they're a pita to adjust.
When I get around to making my holders (if I ever get a round toit) they'll have good ole Holochrome UNF screws.

Steve,
You are correct, they're M10x1.0 threaded. Luckily those set screws are all OK. It's the nuts that are all tapped kiddie wampus. McMaster has the regular M10x1.0 nuts but not the thumb nuts. I'll have to make the thumb nuts. I'll make them out of brass. I don't have a knurling tool so they won't be anything fancy.

Damn!!, I must be extremely lucky, I just got another 30 of the $8 AXA blocks from CDCO, I opened 16 of them up to 3/4" and the other 14 to 5/8", then changed the set screws, other than that all was fine, nothing crooked, stripped or any other defects to make them unusable.
The 10 mm x 1.0 mm nuts are easy enough to find, I buy lengths of 10 mm x 1.0 mm all-thread and cut my own studs as necessary.

Jack,
Maybe his supplier for the BXA size is different from the AXA size. I never use to have these problems with the CDCO tool holders. It's just been the last couple of batches that have been disappointing.
Good idea on the all-thread. I ran out of the set screws so I'll place an order with McMaster for some more of those and also get some of the M10x1.0 nuts. I may as well get some of the all-thread to have on hand.

Ahhh, but I'll bet you haven't tried tightening them down on a tool yet, am I right? 
The last batch I got from CDCO the hex rounded out in half of them on the first tightening. Now I just bin them straight out of the box and keep a large bag of set screws and studs on hand from McMaster as replacements.
I also chase all the threads in the holders before installing the new hardware. It's like a rock quarry down in those holes. 
tools4cheap is looking better all the time.

Willie, we're not talking about the M10 x 1.5 setscrews for clamping the tool in the toolholder, but the fine thread one for the toolholder height adjustment.
I, for one, have 2 boxes of high quality setscrews for clamping in reserve.

Willy,
The set screws I was talking about are the long M10x1.0 not the short M10x1.5. The long ones are the ones the nuts thread on to hold the toolholder at the proper height.
Oops! I should have read one more post before responding. Steve beat me to it.
