ABSTRACT:
An attachment for a conductor wrapping tool for providing a reduced rotation speed for driving a conductor unwrapping bit. The attachment includes a housing having an elongated reduced diameter portion for supporting a drive shaft wherein the housing and drive shaft may be supported by and in driving engagement with a motor driven conductor wrapping tool in place of a conductor wrapping bit and sleeve assembly. The housing supports a two stage planetary gear reduction drive for driving an unwrap bit at a substantially reduced speed with respect to the drive speed of the conductor wrapping tool motor and the attachment drive shaft. The unwrapping bit and drive shaft are coaxial and the attachment is adapted for rapid chucking and removal operations with respect to the conductor wrapping tool.
