I need to drill a hole from bar stock 1.049'' diameter and a lenth of 4.0'' I tried a spade drill, no good, looks like a cork screw, I also tried a fixed drill at 1 inch diameter, then offset the drill .030 in x then ran a boring bar in no good, too much chatter. does anyone have any suggestions, as to speeds and feeds or spade or fxd drill???? This is on a machining center lathe. please help, running scrap?????
