what is a combi drill
CheshireBuilder New Member. The combi drill is a COMBInation of a hammer drill/sds/chizel and drill driver and the drill driver is designed simply for driving screws..ichiecatpugh New Member. previous post not strictly true :-. A drill/driver is just that-a drill with a torque control function which then allows it to be used in a controlled fashion for screwdriving. A combi drill is a drill/driver with the addition of hammer action which will allow drilling in masonry.
