Wera Tools 05003990001 – 817 VDE Kraftform Blade-Holding Handle, 9 mm x 98 mm

Wera Tools 05003990001 a premium VDE bitholding screwdriver solely for Wera VDE blades. The handle/blade system allows for lightning-fast change of the required blade and thus a wide range of applications. Kraftform Plus handle for comfortable ergonomic screwdriving, which avoids blisters and calluses. Hard handle zones for high working speeds, while soft handle zones guarantee a high torque transfer.

Why is the right tool so often missing in the workplace? The reason: too many tools and overly heavy tool bags can make it bothersome to carry keep them with you. So for us it was a clear challenge: to develop a tool that is suitable for a whole host of applications and can be easily taken along to the workplace. Our solution: Kraftform Kompakt tools. A handle into which blades with a range of different profiles can be inserted. Compactly and protectively housed in a light and robust textile pouch – and they are even VDE-tested, too.

The individual testing at 10,000 volts, in accordance with IEC 60900, ensures safe working with loads up to 1,000 volts.

Solely for Wera VDE blades.

Wera produces the Kraftform handle out of several materials with different properties. A resistant plastic is used for the core which ensures that the blade is held securely even under high strain. A softer material is used for the colored soft zones, which provides high frictional resistance and allows the transfer of high forces – resulting in less required screw-driving effort. The red sections with their hard surfaces prevent any “sticking” of the hand to the handle, making rapid repositioning of the hand possible.

The basic idea for the prototype of the Kraftform handle – that the hand should dictate the design – has, right through to today, proved to be correct. In cooperation with the internationally recognized Fraunhofer IAO Institute, Wera developed a screwdriver handle designed to match the shape of the human hand as long ago as the 1960s. After a long development phase, the Wera Kraftform handle was launched to the market in 1968. It has been optimized through the years with new technologies but has kept its proven shape. After all, the human hand has not changed either.
