A great deal of power to meet high demands

With an external ½" (12.7 mm) square retainer as tool holder and the automatic activation of the impact mechanism the cordless impact wrench PIWS 10-20V is a professional high-performance solution for the powerful tightening or loosening of screws and nuts. 

Maximum control achieved by preselectable torque settings

To prevent a damaging of the thread, screws and nuts must be neither tightened too little nor too much. Overtightening is reliably prevented owing to the 4-stage torque selection of the PIWS 10-20V. Select the desired torque of 100 Nm, 200 Nm, 300 Nm or even 400 Nm in advance at the push of a button. After that the torque can be adjusted steplessly and precisely via the on/off switch – but only up to a preset maximum value. Even in the dark the different torque settings can be read clearly on the illuminated LED indicator integrated in the base that holds the battery. With the impact mechanism's pulsating rotational movements of up to 3,000 rpm the cordless impact wrench PIWS 10-20V loosens even seized, cross-threaded or rusted screw connections. You don't even need to set the device down to switch between tightening and loosening screws and nuts; simply actuate the integrated changeover switch for clockwise / counter-clockwise rotation. 

High battery capacity and long runtime

With its untiring, high-performance (Li-ion) Flexpower multi-device battery 20 V / 4 Ah the PIWS 10-20V recommends itself for screwing and assembly work in wood and metal to be performed in the entire house, for repair work on your car, motorcycle or bike or even for the professional application in workshops. To make sure you can start working right away a matching set of sockets of the most common sizes (respective width across flats: 17, 19, 21, 23 mm) is already included in the scope of delivery.

Due to using weight-reduced materials for the fibreglass-reinforced plastic housing and a lightweight die-cast aluminium gear housing the PIWS 10-20V weighs only 2,500 g and so permits a secure grip without tiring even during longer working periods. The soft grip inlays incorporated in the handle ensure a firm grip, but also that the device rests comfortably in the hand. Even long screws are driven in effortlessly since the special impact mechanism of the PIWS 10-20V protects your wrist against the torsional forces. For a maximum of occupational safety the device further comes equipped with a quick stop rundown brake and a start lock preventing an unintentional activation of the impact wrench.

The cordless impact wrench is supplied with a 20 V Flexpower multi-device battery (with a capacity of 4.0 Ah) that is also compatible with other Trotec power tools, with a 1.5 h quick charger with automatic charge termination and a set of 4 sockets. Additionally included is a practical belt clip for the attachment to the left- or right-hand side of the impact wrench's handle. An indispensable tool when carrying out work on a ladder or at frequently changing locations. To keep things in order the entire set is delivered in a robust and stable transport case.

Keep using already available sockets and screwdriver bits. The tool holder of the PIWS 10-20V allows you to use all customary external ½" square socket wrenches. Exchanging the attachments does not require any further tools, the attached socket automatically locks in place. With a (½" square to ¼" hexagon) bit adapter* you can also use ¼" hexagon bits – e.g. the 32-piece accessory bit set from Trotec – for the operation of the impact wrench PIWS 10-20V.
