Cordless impact wrench/driver

The FEIN cordless impact wrenches with 18 V are ideal for fastening and loosening metric screws. The high efficiency of the brushless FEIN PowerDrive motors offers up to 1050 Nm tightening torque and 1500 Nm loosening torque. With the electronic torque adjustment, the torque can be adjusted to the desired tightening torque in 6 steps per screw size. Tightened screws can be easily loosened even after mechanical stress or corrosion influences due to the 10% higher torque in counterclockwise rotation. Depending on the screw size, the torque can be adjusted to the desired tightening torque. Thanks to the innovative FEIN MultiVolt interface, the 18 V impact wrenches can be operated with all FEIN Li-ion batteries of different voltages. The adjustable torques make the impact wrenches noticeably more controllable. The tightening torques of metric screws are specified in various DIN standards and by static calculations. With FEIN cordless impact wrenches and drivers, the maximum torque can be preset in 6 steps. The specified values apply to hard bolting and are accurate to within a tolerance of +/- 10 %. This improves control over the bolting operation and protects smaller bolting cases from damage.

With an impact wrench, screws and nuts can be loosened and screwed in. To do this, the impact wrench uses two torques: the torque caused by the drive shaft and a torque generated by an impact mechanism. By hitting the metal head, a higher torque is achieved, which, however, does not have to be countered on the tool. This is the biggest advantage over a normal screwdriver, which is why impact wrenches are also called impact drivers because of their higher torque. 
They can be used for various applications, especially in the automotive sector as they are suitable for wheel changes, for example. Our cordless impact drivers are designed for particularly hard to reach places and the operation is based on the fact that the components inside the impact wrench are mechanically beaten against each other to generate the torque.

We offer high-quality impact wrench models from FEIN for a wide range of applications in the industry and trade. Explore the range below for further information.  

With brushless motor and 6-stage torque setting. For metric screwdriving applications up to M27. ASCD 18-1000 W34 AS.

• 3/4" square head for holding sockets.
• Maximum release torque of 1500 Nm in reverse running.
• Tapping, recutting and cleaning through threads up to max. M30 using the 3/4" VARIO adapter (available as an extra) and VARIO accessories.
• Up to 600 screw connections (M27) with one battery charge (ProCORE 8.0 Ah).

With brushless motor and 6-stage torque setting. For metric screwdriving applications up to M18. ASCD 18-300 W2 AS.

• 1/2" square head for holding sockets.
• 10 % more torque in reverse running to loosen screws which are extremely tight.
• Tapping, recutting and cleaning through threads up to max. M18 using the 1/2" VARIO adapter (available as an extra) and VARIO accessories.
• Up to 600 screw connections (M18) with one battery charge (ProCORE 4.0 Ah).

With brushless motor and 6-stage torque setting. For universal screwdriving applications including self-drilling screwdriving. ASCD 18-200 W4 AS.

• 1/4" hexagon socket tool mounting for holding bits and socket wrench inserts.
• 10 % more torque in reverse running to loosen screws which are extremely tight.
• 700 screw connections (M18) with one battery charge (ProCORE 4.0 Ah).

• HIGHER PRODUCTIVITY – LOWER COSTS.Tapping, recutting or cleaning an M30 thread with an impact wrench/driver is around 3 times faster than manual recutting or cleaning with a tap wrench (25 to 80 seconds).
• NO NEED TO WORRY ABOUT MOBILE REWORK. The FEIN VARIO accessories turn an impact wrench/driver into a powerful tapper, thereby covering an additional application. You no longer need to rework damaged threads or defective components on stationary tools or by hand.
• WORK WITH JUST 1 TOOL. Twist drill, countersink and tap up to M18 with the ASCD 18-300 W2 AS and recut and clean threads of up to M30 with the ASCD 18-1000 W34 AS without the need for any additional special tools.
• LESS RISK OF INJURY. Very safe to use because there is no kick-back on your hands or arms. A VARIO consumable gripped with positive engagement also ensures a reliable hold even at torque levels in excess of 1000 Nm.

The battery capacity indicates how long the battery life will be. The weight also plays an important role, because a low weight prevents premature fatigue of the arms. Another important metric is the sound pressure level, which indicates how loud the device is in operation.

Impact wrenches are used in many different areas of industry and automotive, as well as in installation companies. The cordless impact wrench from FEIN helps you to screw and loosen screws and nuts with a very high torque – without any kickback on the user's hand-arm system. They can also be used wherever an enormously high torque is required.  FEIN Impact Wrenches can always be adjusted to the size of the screws used. The correct adjustment to the respective screw size is important so that there is no overload or even breakage of the screws.  In addition to threaded screws, Spax screws can also be screwed in.
