Chave de fendas com bateria Wiha 44318 vermelho amarelo

The Wiha 44318 Power screwdriver combines an electric drive with a slim manual option to reduce strain during frequent fastening work. Designed for professionals and serious DIY users, it protects joints and tendons by taking over the repetitive torque while allowing controlled hand tightening for sensitive materials. The kit contains red and yellow slimBits, a USB charger and two standard 18500 batteries for continuous use.

Advantages

The electric drive reduces the time required for fastening tasks to about one third while lowering strain on wrists and muscles. An integrated material-protection function stops the driver automatically at 0.4 Nm so delicate parts are not over-tightened; a sliding switch increases electric torque to 1.0 Nm when higher force is needed. Colour-coded slimBits (red for lower-force applications, yellow Power SlimBits for higher-force applications) help select the correct setting. The tool can also be used manually up to 12 Nm without damage. The ring-mounted switch and smooth rotation improve handling, and the built-in LED ring light ensures permanent illumination of the working area.

How to use

Select the appropriate slimBit colour for the application and set the slide switch to the matching electric force position (red for lower force, yellow for higher force). For sensitive or final manual tightening, rely on the automatic cut-off at 0.4 Nm and complete the fastening by hand. Use the enlarged ring switch to operate the driver comfortably in any working position; the LED ring light can be tapped on for continuous illumination. For tasks that require higher torque, enable the boost position (1.0 Nm) or use the tool manually up to 12 Nm.

Recommendations

Use the red slimBit and red slide position for delicate materials and the yellow Power SlimBit with the yellow slide position for larger profiles. Keep batteries charged using the included USB charger and follow safety guidelines for insulated slimBits when working near live electrical parts.
