Tap Hole Size Calculator

Calculate recommended hole sizes for tapping various materials and much more!

This 3-in-one calculator app features a calculator for recommended hole sizes when tapping various materials, a trigonometry calculator, and a standard calculator for fast and easy calculations.

A user can also achieve torque and horsepower recommendations based on the type and size of tap, material being tapped, spindle RPM and tap style used (hand, spiral point, spiral flute).

Tap application calculations are further enhanced by a fully functional trigonometry calculator which aids in resolving angles in certain tapping applications. Practical tapping applications include determining hole positions and calculating the material depth required to drill a hole at any angle.
