Do the int 30 qc 30 and iso30 all use the same locknut
I know they all have the same taper but the flanges differ but doesn't the locknut just drive the tool up into the taper.
The reason I ask is because I have a Bridgeport textron series II interact with a heidenhain. I have been using qc 30 tooling but I'm thinking that the tool is not being seated in the taper properly because I'm having weird runout readings I put a dowel in a collett holder will maybe have a .005 runout take the tool out back in then will maybe have a .002 runout then repeat the process and maybe get a.001 runout then back to .005 etc.. I'm just wondering if I used a int 30 tool with a thinner flange it would get up in the taper better.
