First of all the bore for the shaft is .001" undersize of the 14mm, not critical as I made the shaft to fit. Run out measures only .001" with a .0005" indicator, quite good.

I bought this to go onto a 1/2”, .500 +- ..005 motor spindle. Advertised as 12mm (.472) and .500, I figured I’d give it a shot but it truly is 12mm, not 1/2”, the quality of the tool is nice, and the er16 collets fit well, so if you have a 12mm shaft this works fine, if you want 1/2” plan on opening up the bore, cuz it’ll be .028” small. End of rant.
