Special Coolant-Thru Adapter Question - ER Style

Suggest calling their 800 number and asking. Their web site is pretty pathetic. The page you reference seems to indicate the top of the shank is tapped 3/8" NPT so you could install a plug. The bit about the side coolant feed with 1/8" NPT is rather unclear as to whether it's standard equipment or an option.

I agree with you about the "plug" in the back... And I think the 1/8" NPT is standard on that particular model only... But we shall see!

I actually called them first... VERY good supplier IMHO. Spoke to one of my main contacts there and he told me it won't work for my application... But that's never stopped us... :)

Figured someone here might have some real-world experience with one.

Joe, maybe I'm confused, but those parts appear to be for a staionary ER holder, IOW for holding a drill bit or other tool in a lathe turret, and having through coolant for the stationary tool.

I can understand why they suggested it might not work.

For a drilling operation, you need a Deublin coupler. Since you make your spindles anyway, the basic need is for the spindle to be hollow, sealed, and fed from the rotary coupler.

What did I miss?

Hadn't considered that... Seems logical now though... Might not be balanced for spinning...

I'm checking that out now.

Could be that *I* missed something.

For a mill, it looks like a completely useless product. The toolholder goes into ... a collet? ;-)

I _know_ that I've seen rotary coupled, coolant through shank small ER collet systems and collets in Europe... But that's no good, since I can't remember where. Sorry :-(

Fahrion or Haimer are making the nicest collets and tool-holders in town. and

Did you find a solution Joe?

Not yet...
