Metric tap drill diameter

Calculates approximate thread depth from a pitch multiplier; it is not a standards-based inspection dimension.

Calculates simplified thread cutting time from thread length, approach length, and feed rate.

Calculates engagement turns from engagement length and pitch.

Calculates helix angle from lead and pitch diameter.

Calculates thread lead from pitch and user-supplied number of starts.

Calculates required thread engagement from axial force, allowable shear stress, and effective shear perimeter.
