Got to try my new Vargus "Mini Pro" boring bar today and was a little disappointed. I got the C06-24W405, pg. 53 here:

Says min bore is 0.230". I was trying to open up a 1/2" hole and no matter what I did the bottom of the insert rubbed with the cutting edge exactly on center. I just eyeballed the top of the insert level and am sure it was very close (bar is round with no flat). The only way I got it to not rub was to move it above the C/L.
Is this normal? What about twisting the bar to a negative rake angle? What am I missing here?
