• Magnetic bit holder for 1/4 - C6.3 tips. Bi-material handle: combination of 2 materials: neoprene and polypropylene. A very powerful couple thanks to the hexalobée form. The 6 lobes wedge fingers naturally during powerful tightening. Speed: thinning of the body of the screwdriver for quick tightening. The advantages of a round-body screwdriver: hand-adapted shape, natural recovery movement. And those of a screwdriver with square or triangular body: development of a powerful torque without excessive tightening effort. Posed, do not roll.
