The innovative Patented DFB dual function bit and sleeve set represents a truly revolutionary approach to wire wrapping, by combining both wire wrapping and unwrapping functions in one set. The bit is precision machined for high quality wire wrapping in the clockwise direction, but functions as a removal tool to unwrap when operated counterclockwise. The user can quickly and easily switch back and forth between wrap and unwrap mode by retracting or extending the retractable sleeve, and flipping the switch on a PTX Wire Wrapping Power Tool. This product, which can wrap or unwrap 22-26 AWG wire, enables the user to maximize operating efficiency while eliminating the need to purchase and carry extra tools. Also, to prevent pin-to-pin shorting, the retractable wire wrapping sleeve is coated with 1000 Volt dielectric material.
