Narrative:

Departing the runway. Accelerating through 80 KTS plane had a bad vibration. I aborted take off but the plane was pulling hard left. I applied hard right brake and full reverse. The plane didn't slow as quickly as it should. Running out of runway I shut down both engines and tried to maintain directional control. Came to a stop 100 yards past the end of the runway. No one was injured; the plane was not damaged nor any airport equipment. The plane was towed back to the FBO and put into maintenance to check the aircraft.
