Tap tool

This tool is used to machine the internal threads in Drilling operations. It consists of two parts: cylindrical and conical. A tool of this type is defined with the parameters shown in the image.

The diameter and the length of the cylindrical tool arbor are defined as Arbor Diameter and (Total Length - Shoulder Length), respectively.

The Shoulder Length value must be greater than or equal to that of the Cutting Length, and equal to or smaller than that of the Outside Holder Length.

The default Arbor Diameter value is equal to that of the Diameter, and the Shoulder Length value is equal to that of the Cutting Length.

Units

For parts in metric units, the default unit is Pitch(mm). You can also recalculate the value in Pitch (inch) or TPI at your convenience.

For parts in inch units, the default unit is the TPI (threads per inch). You can also recalculate the value in Pitch (mm) or Pitch (inch) at your convenience.

Parameter limitations

Parameter	Range
Tip Diameter (Tip D)	Tip Diameter (Tip D) < Diameter (D)
Chamfer Length (Ch.L)	Chamfer Length (Ch.L) < Cutting Length (CL)
Pitch	0 < Pitch < min (Diameter (D), Cutting Length (CL) )

This tool can be used only in 2D Drilling/3D Drilling operations.
