Need to find the right drill 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. There is also detailed information about the commonly used sizes of wood screws.
