It's a Valenite tool holder. It's designed for bits with the hole in the center so I just machined the little stem off.mitch wrote:Cedar can you post a few more pics of this. Did you make the tool bit hoder also.Cedarmachine wrote:Here is the CBN holder I made for my machine. Uses 3/8" inserts.

Re: Cbn
Question why would one choose 3/8" vs 1/2" which is better at what. I have only used 1/2" before and getting a holder/head for my machine its time to make a choice for the bit size.

My thought was, that the bit would be a little more stable in the holder, for one.
Also, the "cutting edge" has a smaller radius on the 3/8 bit. I think less of the actual bit is doing the work and keeps the cut from possibly chattering.
Re: Cbn
I want something like this for my machine. Can you post more info/pics on this? I have a post on the shop tech section on this subject also. You can see a kit just like what you made but adjustable. http://m.ebay.com/itm/151248065961?nav=SEARCHPHANTASM wrote:pic

Re: Cbn
I was looking at doing the same thing and came to the same conclusion. Comparing it to a 1.5" iron "flywheel" it has to move or chatter a bit more if you tried to do a heavy cut. All depends on how much you want to cut at once. Place I worked at on the Rottler I could do .005-.008" without problem in aluminum, my friends Comec is worn enough that he only does .001" per pass which to me takes too much time if in a production setting.
