Internal threads are cut by Taflet series has good points

Comparison of TAFLET Series (Thread forming tap) and Cut thread tap

Item	Cutting Tap	Taflet	Characteristic of Taflet
Breakage			Hardly breaking because there is no flute
Chips trouble			Free from troubles because no chips are produced
Precision of internal threads			Dispersion is small because forming threads
Surface roughness of internal threads			Extremely good quality because of sliding on the tap face
Tapping torque			1.5 to 2.5 times higher than the cutting tap
Strength of internal threads			Strong because fiber flow is not being cut by plastic cutting
Work material			Limited to high-ductility materials

Good surface of work material

Higher thread strength because fiber flow is not cut
