I have a Albrecht 130 keyless chucks that requires a J2 arbor. Does anyone know of a supplier / manufacturer with a real precision ground shank? I can't see sticking a $500 chuck on a $4 shank.

I did a double take at the price on Shars it was so low
I dont mind paying I just need to know who to trust
I have a Jacobs arbor on a Jacobs precision chuck & its a good combo. Bought many moons ago when prices weren't quite so crazy. Now I cant recall if they had classes of runout on the arbors as the chucks. I might have them mixed up with someone else, but the story was they farmed out the regular line offshore & kept the precision stuff for now. This place is in Canada at least.

Thomas Skinner might have more offerings but their online catalog went for sh*t so it's a call-in thing.
Having said this I have since acquired a few tools including (integrated) chucks from GS & they are just as accurate, under 0.0005" when new. But probably half the price. Sold through Sowa type distributers.
And Albrecht themselves sell arbors if you really feel inclined

Always specify Jacobs arbors to serve the finest performance from Jacobs drill and tap chucks.

Thanks, I happen to trust them too, but when I searched MT2 JT I did not get a result. Only when I just went back to their site and search arbors did I find their listing. At $12 there is little risk in trying.

I'd like a albrecht given that their shanks are ground concentric within 0.0001" but no MT offerings from them. I'll call newman and see what their jacobs pricing is.I have a Jacobs arbor on a Jacobs precision chuck & its a good combo. Bought many moons ago when prices weren't quite so crazy.

A couple years ago, I needed an arbour and tried 2 of the KBC house-brand pieces. On both, the Jacobs taper side was ground in an egg shape! Out by as much as 3 thous from round. At least I was able to return them easily enough. The Accusize arbour had no measurable runout. FWIW.
