Cordless impact wrench PIWS 10-20V

This 20 V battery with 4 Ah offers considerably more power and endurance for screwing and repair work on your car

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.

Changing tyres like a pro

Using a good old spider wrench for swapping from summer to winter tyres or vice versa takes a great deal of time and effort. There are always seized screws and nuts to be loosened or properly tightened when carrying out repair work on a motorcycle, engine or gearbox. Using the battery-powered PIWS 10-20V these tasks can be accomplished in next to no time – just like they do in motorsports – but without a compressed-air hose or an annoying cord.

Practical tip: With the PIWS 10‑20V flat tyres no longer have to be dreaded. If you have the compact cordless impact wrench in your boot, the spare tyre is assembled with lightning speed even in the gathering darkness at nightfall. The integrated LED work light ensures the best possible illumination of the working area. For that sense of safety: Once charged, the Flexpower multi-device battery supplies the full charging capacity even after a longer period of non-use.

Speaking of torque ...: The torque of an impact wrench is a safety-relevant factor when changing tyres. The torque varies depending on the type of vehicle and wheel rim. Hence you should contact your vehicle / rim manufacturer and enquire about the recommended value. With 4 selectable torque settings ranging between 100 and 400 Nm the PIWS 10-20V provides enough power for any vehicle and tyre combination. A set of sockets suitable for the most commonly used wheel bolts is already delivered along with the device. A suitable key or adapter may be required for wheel locks.

Quality & performance – it's in your hands

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.
*Not included in the scope of delivery.

Twice as long-lasting with the Flexpower multi-device battery 20 V / 4 Ah

The lithium-ion battery of the PIWS 10-20V without self-discharge or memory effect is a genuine power pack. He who is not fully satisfied with 20 V and 2 Ah, can further benefit from the substantially increased endurance of this prime battery.

100 % more power than a battery with 2 Ah

Compared to a battery with 2 Ah the charging capacity of 4 ampere-hours enables twice the runtime. The full battery capacity is available from start to finish without any signs of weakening towards the end. Such a great deal of power and endurance also impresses in practice and you get things done more efficiently! 

Fully charged in only 90 minutes

At the push of a button the 3-stage battery level indication integrated in the housing indicates the battery status – even if the battery is not connected to the device. The charging process is completed in next to no time: By using the quick charger included in the scope of delivery a completely discharged battery will again be ready for use after 90 minutes. 

The Flexpower system is highly compatible

The Flexpower multi-device battery 20 V / 4 Ah can also be used in combination with other Trotec power tools. Besides prospective further power tools the battery can be attached to the convenient work light PWLS 10-20V. Should you already have a 20 V Flexpower multi-device battery with 2 Ah, it can also be connected to the impact wrench PIWS 10-20V. It makes for a good spare battery in any event.

Premium branded battery for constantly full power

Premium branded battery

By now, lithium-ion batteries are widely distributed, after all they come without memory effect and self-discharge. Plus these batteries can be disconnected from the charger and used right away without it affecting the battery’s lifetime. But “lithium ions” is a generic term used for batteries of various qualities and made of diverse electrode materials; including those with a perceptibly weakening performance once the battery charge decreases.

Lithium-ion batteries supplied by Trotec are high-quality premium branded NMC batteries with a high energy density and charging voltage lasting until the end without exceptions – guaranteed! Compared to conventional lithium-ion batteries the performance of our premium branded batteries does not decrease even as the discharge increases.

Consequently, you benefit from lasting maximum power even with an almost empty battery. During longer operation only the battery charge decreases, never their performance – that is the added value of Trotec’s premium branded batteries!
