Automatic bit stroke

The bit stroke is the path which the tool travels during the screwdriving process from the resting position until it has reached the screwdriving head. A pneumatic cylinder performs the first stroke which positions the tool on the screw when the bit stroke is automated. The automatic bit stroke in hand-held screwdrivers facilitates the handling for the operator and may reduce the cycle time – also in automatic screwdrivers.
