Abstract: A bit holder for holding and driving a screw with a screw head into a fastening base, comprising a clamping region for connecting the bit holder to a driving tool and a bit receptacle for inserting a bit suitable for driving the screw. The bit holder has at least one magnet arranged eccentrically relative to the bit holder with one pole facing the screw head. The at least one magnet is held floating on a magnet holder in relation to a bit held in the bit receptacle, so that the pole face of the magnet can align according to the contour of the screw head in order to hold the screw on the bit holder in such a way that the bit engages torque-locked in a rotary driver contour of the screw head.

Abstract: The disclosure relates to a bit holder 1 for holding and driving a screw 3 with a screw head 4 into a fastening base, comprising a clamping region 2 for connecting the bit holder 1 to a driving tool and a bit receptacle 16 for inserting a bit suitable for driving the screw 3. The bit holder 1 has at least one magnet 7a-7f, 7.1a-7.1f arranged eccentrically relative to the bit holder 16 with one pole facing the screw head 4, wherein the magnet 7a-7f, 7.1a-7.1f is held floating on a magnet holder 8, 8.1 in relation to a bit 6 held in the bit receptacle 16, so that the pole face of the at least one magnet 7a-7f, 7.1a-7.1f can align according to the contour of the screw head 4 in order to hold the screw 3 on the bit holder 1 in such a way that the bit 6 engages torque-locked in a rotary driver contour 5 of the screw head 4.
