Drill Calc
iPhone Software for Drill Bit and Tap Calculations
Drill Calc calculates the correct drill bit size to use for threaded holes, based on the bolt (tap) diameter and thread pitch and percentage, for both inch and metric threads.
It also has tables of standard inch fractional and numeric drill bit sizes.
