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.
