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.

I am a hobbyist machinist. I am always using Drill Calc for looking up drill sizes when I am threading. One feature I would appreciate is an all encompassing decimal lookup chart. This single chart would contain fractional, lettered, numbered and metric drill sizes. I also would find it helpful if you supplied the data for doing external threading.

Functionality of app is great! Good clean layout. I agree that pipe theads would be a great addition, as well as fine threads for metric taps. Clearance drills, counterbores, and reamer drill sizes would also be a welcomed upgrade. I would pay extra for those options even. Keep up the good work

This app puts at my fingers all the data I could ever need in the machine shop when tapping time comes around. Very detailed and accurate.

This is great; all the Inch - Metric and Pipe Information in one app. We deal with both english and metric taps at the machine shop I work for, so this makes it a very handy app.

As far as I can tell does not have though-hole measurements, which would be easy to add to each bolt size and very useful
