Metric Drill Bit Sizes Metric drill sizes are used primarily in Europe and use metric units to measure the drill bit diameter There are a variety of standards used to define drill sizes, the most common one in the UK is the British Standard BS 328 set which includes twist drill bit sizes between 02 mm and 25 mmThe standard drill size and it's decimal equivalent in inches For example, a 5/16 drill size equates to 0313 inches for soft metal drilling Getting Your PreDilled Hole to the Right Size The last segment of the tap drill chart are the columns on the right third of our tableNominal Size ø d1 UNC UNF UNEF UNJC UNJF M MF MJ NPSM NPSC NPSF Rp_ (BSPP) G STIUNC STIUNF STIM LKUNC LKM BSW BSF Pg Tr TrF Rd inch Fraction Wire letter mm 00 M10x125 G 1/8 LKM10 00 MJ10x125
