Hi, I made some easy change tool holders for my Boxford VMC and have a few spares if anyone is interested.
I have ER25 and ER16 holders that I machined from 316 stainless in one hit so all diameters are true.
There is an M8 pullstud hole in one end and they will come supplied with a nut.
40 delivered.
PM me for details/photos.

Hello James, I have a couple of ER16 holders already but would be very interested in the gcode if you turned them using cnc, please? I'm interested in making some other types of holder.

Only for curiosity, are the holders hardened or soft?

You cannot harden 316 sst much. maybe get to 40hrc. And it galls unless lubricated

Sorry, I don't know the english steelcodes, We in germany have a different Sytem, so in many other countries.
