Through-Tool Coolant on ER16M Holders

Lathe
1

I see the ER16M holders available from Tormach note that there’s a 1/8 NPT coolant through hole. I was wondering if anyone has any of these holders and whether there are provisions for a 1/8 NPT fitting in the end or if they’re simply drilled 1/8" dia. through?

Thanks,
Matt

@Matthew_Herd I recently added a few of these to the 15Lin the showroom. These have threaded NPT holes in the back.

Thanks! That’s what I needed to know.

I should also note that these and at least the regular ER16 holders have a set screw in them. What I didn’t realize at first was that the socket head is facing the ER collet side. So they all have a through hole. Also, through tool coolant is now working great. Handy for deep drilling!
