A drive system cooperates with other tools, such as the drive mechanism of a socket type ratchet wrench to enable a user to use the wrench for its intended purpose at high speed by pulling an endless belt. The belt is contained within a chamber created by the attachment system in a manner to allow the belt to engage with an outer surface of a pulley. The pulley connected to the drive shaft of the socket type ratchet wrench to cause force to be transferred from the belt to the wrench drive shaft. The system utilized a cover operably coupled to the pulley to contain the belt while minimizing interference with the wrench. The cover contains the belt while also allowing an opposite end of the belt to hang loose and thus be easily accessible by a user.
