Good morning guys,

just curious, has anyone ran any of these WIDIA KM63 connection boring bars?

this will be used on a mazak QT450M lathe
50mm VDI connection to the turret

bar is a 2.5 diameter bar with a total 22.00 overhang. this bar is held by the KM63 connection. ( no split sleeve )


i am a little weary of the connection KM63 holding the weight and rigidity.


i feel more confident in a split sleeve holder set up..



what do you guys think?

I can tell you from experience that capto can handle that and more with no problems whatsoever.

I have no experience with KM but it's proponents like to claim that it's just as good as capto. I am skeptical of that but...

Anyway, the I suspect the VDI50 will be the weak link in any case.
