What's the taper on this?

[la_coterie]

Not sure if this is the correct area for this, but I'm sure someone will say if not

I've a high frequency motor with this taper on the end, can anybody tell me the style of taper and where I might get a chuck for it? The large end's about 19mm - 3/4" I'm looking for a small collet chuck, ER16 or 20.

It looks kind of like a JT33 drill taper, but you can't use those for milling or routing without a draw bar.

yeah, that's a lot of taper to use for milling. Probably a high speed drilling head.

I think that it's bigger than a JT33 taper and there's a thread in the shaft end, presumably for holding "whatever" on the end.

I'll check out the JT taper theory anyway & report back
