Drilling
Folks,
Seems like you are expecting a drill bit to give +/- 0.001 accuracy. I would say this is probably not the case. They way we always machined holes with that precision was to
drill a little small and then ream it to the correct size. A ream will give much better accuracy than a drill bit will.
Just my $0.02

In 2012, we built our best machine ever. Some visitors to our pit were visibly disappointed to find that our machine was a pile of extruded aluminum and urethane belting, just cleverly arranged and programmed. - OZ_341 [more]
