A: Partial profile inserts don't cut the minor diameter (do not make calibration) while full profile inserts cut the minor diameter.

A: One insert covers a wide range of pitches.

A: The insert nose radius is smaller than defined in the standard. This results in a thread that is not according the standard and in shorter tool life.

A: To support the insert cutting corner, to protect the holder body in case of insert breakage and allow the adjusting of the helix angle by changing the anvil.

A: Yes, it is possible (remember! lead = pitch multiplied by the no. of starts).

A: Flank infeed has a better chip control and surface finish in most raw materials and applications.

A: We recommend and use the tangential ARC method.

A: A profile distortion will occur.

A: The difference between a thread form according to the standard and the actual thread form on the workpiece.

A: You make once cycle, then move the tool in a "z" direction and machine a second cycle.

A: It is difficult to give a general answer because it depends on workpiece material, machine conditions, pitch and clamping system. Please ask us for your specific application.
