I have never really seen any metric drill bits with 0.05 mm. 'resolution'
I have never really seen any metric drill bits with 0.05 mm. 'resolution' The common as muck ones are in 0.5 mm. steps and the finer steps are 0.1 mm. wich I would think would be close enough for Rock'n'Roll
I've frequently used drills that are 1/64th larger than the reamer as a starting hole. It may not be ideal, but it has worked for me. I'd say you'll have no trouble with that in either aluminum or brass.Others please feel free to correct me if you disagree.Kim
