Claim:
1. A hydraulic rotator converter for attachment to a hydraulic impact hammer having a hammer housing and a hydraulic piston, the hammer housing comprising bushing assemblies and a locking mechanism, the hydraulic piston arranged to generate a pounding action, said converter comprising: mounting brackets configured to attach to the hammer housing; and a hydraulic rotator assembly arranged to rotate a drill bit, the drill bit having a drilling end and a second end, the drilling end comprising a flute section and a shaft extended from the flute section, the flute section comprising a helical flute, the shaft dimensioned to receive a drill bit end, the second end engaged in the bushing assemblies and the locking mechanism in the hammer housing and arranged to be contacted by the hydraulic piston so as to allow the hydraulic piston to generate the pounding action on the second end of the drill bit while the drill bit is rotated by the hydraulic rotate assembly for drilling one or more holes on a hard surface, each hole having a hole size, wherein the hydraulic rotator converter is arranged to disengage from the hammer housing so as to allow a hammer tool to engage with the bushing assemblies and the locking mechanism in the hammer housing, the hammer tool having a tool body with a diameter greater than the hole size arranged to receive the pounding action from the hydraulic piston for pounding over said one or more holes.
