Looking to learn from those with more experience in this regard. I typically do this sort of deep boring with a brace and auger bit, however I have a fairly critical installation coming up that needs some serious accuracy.
I will be using a Bridgeport milling machine to do the boring, but I am interested to know which type of bit is the least effected by deflection in the cut.
I have some ideas, but I'd prefer not to color the responses, only thing of course is that I would like the bit to be initially shorter, then once the cut proceeds about halfway I will be able to add an extension and bore the remainder.
Thank you
Brian
