But there's also so much torque that without a tommy bar, the taper comes lose from the tail stock and/or the jacobs taper breaks free of the drill chuck. Still, maybe I can do things differently now. I just figure that if there's that much resistance, the pilot serves a good use. I never considered that it may be less accurate, but If I'm drilling that large, I"m probably going to bore it out anyway. Something to remember though.With a split point you do not need a pilot hole as long as the work is perpendicular to the drill and the surface is reasonably smooth. Saves time, more accurate holes.
