Wera, Kraftform 1/4" bit holding Turbo bit driver handle

The 826T Kraftform bit handle functions as a regular bit-holding handle, but with the push of a button a one rotation of the handle becomes, through a clever mechanical miniaturized transmission system, a 'turbo-charged' 4 rotations of the bit. Complete with a Rapidaptor quick-release magnetic chuck technology so nothing will slow you down in your superhuman screw driving actions. Takes all regular 1/4" drive bits and overall length is 146mm. Fits: > 1/4" Hexagon bits
