According to the specific info I've received from my HFO last Eastec, yes, the BMT65 turret is using the standard tooling.
And another tidbit for others.
Though it isn't clear on the Haas brochures, the BMT65 turret is available for all ST20 and up machines without the live tool drive.
So, if someone want to beef up the turret size ( more weight ) and have more clearance ( I sure do ) then the $6500 BMT65 turret-only option is there for ya.
