Keller Super series riveting hammers are designed with an accurately timed cycling valve which provides smooth consistent operation of the tool. Having this precisely timed valve allows for a reduced weight of the tool as the handle thickness can be reduces because not as much excess weight is needed on the back end of the piston travel to overcome the vibration resulting from an inaccurate timed valve.
