Thread Depth Tap Calc
Tap drill depth calculator
$0.29 · Designed for iPad. Not verified for macOS.
Thread Depth Tap Calculator is a paid standalone utility for quickly checking threaded hole parameters in workshops, repair work, hardware machining, and engineering prototypes.
The app uses metric thread size, target effective thread depth, plate thickness, blind-hole allowance, and drill point angle to calculate recommended tap drill diameter, minimum drilling depth, tapping depth, remaining safety margin, and breakthrough risk. You can also create frequently used size templates and save local project records for fast checks before repeat machining.
All calculations are performed locally on your device. No login is required, no internet connection is used, and no user data is collected.
