Drill Calc

       iOS Universal

Need to find the right bit size for a hole? 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. Close and tight fit hole sizes for many popular drill sizes are also displayed.

It also has tables of standard inch fractional and numeric drill bit sizes, as well as complete information for various pipe sizes.

Buy your copy of Drill Calc today, and put away your drill chart.
