Kraftform
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 recognised 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 optimised through the years with new technologies, but has kept its proven shape. After all, the human hand has not changed either.

Rapidaptor holder
Rapid bit change without needing any additional tools. One-hand operation with a freely spinning sleeve for simplified guidance of the tool.

Rapid-in and self-lock
The bit can be pushed into the adaptor without moving the sleeve.The lock is activated automatically as soon as the bit is applied to the screw. Bits are held securely and wobble-free.

Rapid-out
Simply push the sleeve forward to change the bit. The spring mechanism lifts the bit off the magnet and unlocks the tool. The bit can be easily removed. The rapid-out function makes it easy to remove even the smallest bits without extra tools.

Chuck-all
The Rapidaptor quick-release chucks hold 1/4" DIN ISO 1173-C6,3 and E 6,3 as well as Wera series 1 and 4 bits.

Single-hand function
Every function of the Rapidator quick-release chuck, such as inserting or releasing bits, can be carried out with one hand. This is faster, more economical and more ergonomic. There are no unnecessary manoeuvres.

Rapid-spin
The free-turning sleeve allows screw steadying at the start of the screwdriving process. This makes it easier to apply the tool to the screw and prevents slipping. It can also be used as a short extension for 1/4" applications e.g. in combination with the Wera Zyklop Ratchets.
