Abstract (en)
[origin: WO9414576A1] The invention concerns a tool with structured working surfaces which transmit torque when applied to a work piece, in particular a screwdriver bit. In order to create a tool with a working surface that is optimally suited to its purpose, it is proposed that it should be designed either as a moulded part of sintered powder metal such that the roughness resulting from the grain size of the powder metal creates the optimal structure in the working surface for the transmission of torque, or alternatively should be provided with a surface with rolled nubs.
