Claim:
1. A bit holder comprising: a main shaft, the main shaft comprising one or more projections; a sleeve, the sleeve comprising a protrusion that extends radially along an interior face of the sleeve a distance away from the distal end of the sleeve, the sleeve extending around the circumference of the main shaft and extending a distance along the axis of the main shaft; a collet, the collet comprising one or more slots extending from a distal end of the collet to a distance away from the proximal end of the collet and a ramped interface beginning a distance away from the distal end of the collet and ending at the distal end of the collet, the ramped interface expanding an outer diameter of the collet, the collet extending around the circumference of the main shaft and extending a distance along the axis of the main shaft between the main shaft and the sleeve; and a spring extending around the circumference of the main shaft and extending a distance along the axis of the main shaft between the sleeve and the collet, wherein the one or more projections of the main shaft are configured to travel along the one or more slots of the collet, wherein the one or more projections of the main shaft extend away from the main shaft, through the one or more slots of the collet and compress the spring against a proximal end of the sleeve as the sleeve is slid towards the distal end of the main shaft, wherein a groove on the exterior face of the collet, a distance away from the distal end of the collet, is capable of engaging the protrusion and maintaining the spring in a compressed state.
