It is frustarting some days. You get nitro it won't break as much cause it may not start every time. :D
Besides it don't have the same torque curve. I used a drill bit I had laying around that I broke off. I can't recall the size. I used a hardened rod in the other. It is holding well so far. If you take the points off the hex it may fit a little tighter.
