Abstract: An bit driver apparatus having three joined hollow tubular sections with a flexible cable member extending through the hollow portions usable when tight turning adjustments are needed, such as in motorcycle carburetor adjustments. A rotatable handle is fixed to one of the cable's ends and a magnetic bit holder is located within the opposite hollow section such that rotation of the handle causes the holder and its mounted bit to rotate and turn an engaged screw or nut. The second joining hollow second between the other sections is bent at an angle of about 45 degrees with respect to the first handle section and the third bit holder second is joined to the second section at about the same angle but extending in the reverse direction. A supporting outer sleeve provides lateral support for the bit while in its holder.
