The new STA Synchro Tap Adapter was designed specifically for ER collet chucks and driven tools and allows for synchronised thread cutting and forming to be achieved with all suitable machines. The STA Synchro Tap Adaptor with quick change saves considerable time and optimises tool life.

Used with ER collet chucks and driven tools, and manufactured to ISO 15488, Synchro Tap Holders are the best way to dramatically increase tool life in a rigid tapping environment.

The tension and compression length compensation, (+/- 0.15mm) in combination with radial dampening effect, compensates small synchronisation and location anomalies and dampens excessive forces acting on the tap. This allows the tap to cut more efficiently, decreasing torque loads and increasing production. Testing shows an up to four times increase in tool life.

Some advantages of the STA Synchro Tap Adapter include: Minimum compensation on tension/compression; reduction of the pressure on the thread flanks; compensation of the synchronisation error, while reversing the spindle; higher life time of the taps, less number of tools required; reduced risk of tool breakage; and better thread quality.

Synchro Tap chucks not only increase tool life in rigid tapping, but they can also be used for high speed Synchro Machine Taps with two- to three times the cutting speeds of normal taps.
