Description
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.

Ratings and Reviews
Good, but could be better
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.
App fail to load
I was unable to access the app after downloading it. Restarting my phone did not repair it. Money wasted.
Works well
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
