Ok, metric sizing is better but we have fractions here is the US. At least they're consistent in there sizing increments. But, who came up with the number and letter sizes? There is no consistent dimensions increments between sizes and in the case of letters the "F" and 1/4" are the same. WTF is up with that?? It has never made any sense whatsoever. How about a drill set that starts at .015" and goes to .505" in .01" increments? Much more useful.
Don't even get me started on tap shank sizes!!
