Abstract:
1. A bit holder comprising: a shaft having a proximal end adapted to couple with a driver, and a distal end magnetically coupled to an interchangeable bit; an outer sleeve surrounding the shaft in an unlocked configuration to form a socket with a non-circular cross section near the distal end of the shaft; at least one interchangeable bit comprising a working end and a proximal portion with a non-circular cross section complementary to the socket, the proximal portion including a plurality of contoured portions that permit the interchangeable bit to articulate in the socket, the interchangeable bit further including a relief located between the working end and the proximal portion configured to permit articulation of the interchangeable bit and to engage with distal end of the outer sleeve to limit articulation relative to the shaft; and a locked configuration for the outer sleeve such that the distal end of the outer sleeve engages with a body portion of the interchangeable bit to retain the interchangeable bit generally aligned with a longitudinal axis of the shaft.
