I'm at my wits end on this one. Have .201 hole in a .75 diameter 6061 alum part. The hole is 1.25 inches long and I cannot for the life of me get it to drill straight without wandering off. I am using a .250 parabolic flute drill from OSG. Any input and help on this will be much appreciated. I have tried all the speeds and feeds and called osg and all that, but it walks over .010 and I cannot get it to stop. Thanks
