Impulse Screwdriver with Automatic Shut-Off

Low-vibration screwdrivers with an integrated hydraulic impulse mechanism

  • low vibration
  • low noise level
  • optimal design of the open-pored plastic grip
  • high repeatability

The low-vibration impulse screwdriver allows the fast tightening of fasteners without any tangible torque reaction.

The ergonomic inline or pistolgrip design enables fatigue-free operation despite the high torque output.

The impulse tool is a similar design to an impact driver, however with integrated hydraulic impulse unit.
The torque output is controlled by the frequency, (= pulse per minute) and by the adjustment of the pulse unit. When the preset pressure in the pulse unit is reached, which is relative to the torque output, the driver shuts off.
This shut-off transpires prior to achieving the theoretical maximum possible torque and therefore no hammer effect occurs, as with standard impact drivers.

This technique of regulating both pressure and frequency, allows a torque accuracy of ±5 % standard deviation for pulse drivers with a torque setting even below 10 Nm (88 in.lbs). To enhance the versatility of this tool, the reverse torque is 20 % higher than the seating torque, to assist in rework application.
