Features and Benefits

Tension and compression tapping styles are engineered to automatically compensate for machine feed, pitch and tap rates. They feature a spring design that allows the tap to float during the cutting cycle without affecting the pitch.
Taper shanks maintain balance and rigidity during high speeds and heavy-duty applications. They have smaller diameters than straight shanks.
