Now I know that if I do the best job I can it will be all that's needed. And I intend doing the best job I can.
Just reading up on the drill tip angles, it would seem to me very likely that the 135° angle is the one. All the stuff I read suggests that the 118° drill is most efficient in 'soft metals' and cites aluminium as the standard there while the 135° drills come into play in harder metals. And while it would be nice to know just to be more correct, it's also good to know that my tooth fillings are likely to stay in as I cruise the B350 at 2,500rpm.
