I was gifted with 2 packs of Sandvik Coromant inserts. The gifter swears they work miracles on hard steel. I did not get the tool holder or clamp for these inserts. The inserts are marked SNGN 12 04, 16ESNG 434A, and 620.
I have researched these inserts and found lots of info on metals they will work on, speeds and feeds, but cannot find an insert holder for them.
Can someone with knowledge of these inserts please explain how to find the insert holder and clamps for these inserts? If I can get the proper clamps and spec for the tool holder, I think its within my capabilities to make the tool holder.

The difficult takes me a while, the impossible takes a little longer.
Good timing. I got a bunch of large carbides yesterday at a yard sale. Some square, some triangular, even some three-point threading carbides I've never seen before. I'll be watching for pointers to make several different holders.

If you can't get one, make one.
Hawkeye, proud to be a member of MetalworkingFun Forum since Jan 2013.
Hawkeye, I've posted my question on 6 forums and the only result Ive gotten was to look on the Sandvik site, which I already had done. Unless I am just not understanding what I see, I found nothing there but the description/spec of the insert.
If it was a holed insert,I would be o.k. but these are clamp type.

Chuck,
This is a holder from Iscar, I know it wasn't what you asked for but it may help. http://www.iscar.com/eCatalog/Family.asp...pe=4&rel=I
I have to say I have never found the Sandvik web site very helpful - maybe it is just me.

Well Dave, at least you found something! I've been admonished on another forum that the Sandvik site has all the info I'd ever want, but Da--ed if I can find it. Plus, I don't want to spent $80+ for a tool holder... Now the Sandvik link that was provided doesn't load...
Thanks Dave and all that responded.

Those are more commonly used in milling applications than turning. There are holders for turning with them, but if you already have a holder for SNMG43x size inserts (as I do) then you just need a different anvil (seat) and clamp. Most holders would use an eccentric screw in the middle and a clamp over the top. For those inserts you would switch to a screw-down anvil with no eccentric sticking up, and a flat clamp.
Once you have that, pray for the inserts.
They are a non-reinforced Al²O³ ceramic insert, intended for milling cast iron. You would have an easier time finding a milling cutter that takes them. In fact, I may have one you could have for CHEAP.
