Perfectly formed threads and accurate diameters without eccentricity by milling the crest of threads and tapping simultaneously.

Uniformly accurate tapping even if the drilled hole is misaligned.

Negligible finishing of casted holes on aluminium die castings; rough holes in die castings can be directly tapped to maintain a uniformly accurate internal diameter.

The End Mill blade neatly trims seams, eliminating chipping of seam crests, burrs and hair chips.

Threads are finished seam-free, eliminating plating-chemical contamination for high resistance to corrosion.
