Type HF Tap Holders
The EMUGE tap holders type "HF" are mainly used on big drilling machines and boring mills and are available in two sizes.
Note: The tap holders type HF are suitable for cutting right-hand and left-hand threads.
The tap holders of this type are designed for cutting big threads. Furthermore, the drilling or countersinking operation may be executed without changing the tap holders by blocking the length compensation via a locking screw.
The advantages resulting from this are:
The change of the tools is executed via quick-change adapters type HE.
Both sizes are equipped as follows:
Integrated overload clutch with maximum torque HF20: 1300 Nm,
Integrated length compensation on compression and on tension.
On option available with
On machine tools where the spindles are equipped with internal coolant/oil supply, the thread cutting cycle is especially efficient if the coolant/oil comes out through an axial borehole in the tap or along the tap flutes. Advantages:
To ensure a trouble free function of the length compensation, the according coolant pressures should not exceed the recommended limits.
