Technical overview
The PARKSIDE® Electric Impact Wrench PDSSE 550 A1 is a 550 W corded tool designed for tightening and loosening screws, nuts and wheel fasteners. Its impact mechanism provides up to 500 Nm of loosening torque and uses a 1/2″ external square drive.
Key features
▸ Maximum loosening torque of 500 Nm
▸ Maximum tightening torque limited to 100 Nm
▸ 550 W corded electric motor
▸ Selector for clockwise or anticlockwise rotation
▸ 1/2″ external square drive

How it works and what it is for
The motor operates an impact mechanism that delivers repeated torque impulses to the fitted socket. Clockwise rotation tightens fasteners to a maximum of 100 Nm, while anticlockwise rotation provides up to 500 Nm for loosening stubborn connections. It is suitable for fitting car wheels and working on larger screws and nuts.
