A tool holder comprising an elongated connector means having a first end and a second end, where the elongated connector means has a central longitudinal hole, of a cross-section corresponding to a cross-section of a mounting portion of the tool bit, at the first end, and a tool mount at the second end, and a first sleeve arranged to reciprocally slide over the connector means between a first end position and a second end position, the first sleeve having a third end facing the tool bit and a fourth end facing the hand tool. The connector means has a substantially cylindrical tubular first collar arranged on the connector means adjacent the first end, the first collar having an inner diameter which is cooperating with an outside diameter of the connector means, to allow the first collar to rotate on the connector means, the first collar further having a first recess to hold a first locking ball, and a second recess and a third recess arranged on an outer surface of the connector means adjacent the first end, the first locking ball being movable between the second recess and the third recess by rotation of the first collar, and the first locking ball being held in the first recess during rotation of the first collar, so that the first locking all is seatable into either of the second or third recesses, the first collar further having a fourth recess for holding a substantially cylindrical pin, which pin rotates together with the first collar, a part of the pin reaching out into a slot arranged in the connecting means, the slot and the pin being located so that, when the first locking ball is seated in the second recess, the pin is at one extreme of the slot, and when the first locking ball is seated in the third recess, the pin is located at the other extreme. Retention of the tool bit is enabled by offsetting the hex opening in the first collar to engage the slot in the bit.

1. A tool bit holder for use with a tool, th tool bit holder for holding a reversible tool bit, the tool bit holder comprising; a tool bit holler body; a shank provided on the tool bit bolder body, the shank for mounting the tool bit holder onto the tool; a tool bit socket provided on the tool bit holder body, the socket for receiving the reversible tool bit; a locking collar engaging the reversible tool bit and preventing removal of the reversible tool bit from the tool bit socket; and a stabilizing sleeve slidingly telescopingly mounted on the tool holder body and movable between a first position in which the stabilizing sleeve is extended over the locking collar and the tool bit to stabilize a workpiece engaged by the tool bit and a second position in which the stabilizing sleeve is retracted from the reversible tool bit. 2. The tool bit holder of claim 1, wherein the tool bit connector is a receiving cavity having a cross-section corresponding to a cross-section of the reversible tool bit. 3. The tool bit holder of claim 1, wherein the tool bit connector is a receiving cavity having a hexagonal cross-section. 4. The tool bit bolder of claim 1, further comprising first and second detents provided on the tool bit holder body, the first and second detents corresponding to the first and second positions of the stablizing sleeve. 5. The tool bit holder of claim 4, wherein the detents are defined by annular rings provided on the tool bit holder body, each annular ring for engagement with a corresponding annular recess provided in the stablizing sleeve. 6. The tool bit holder of claim 5, wherein the annular rings are mounted in annular grooves provided on the tool bit holder body. 7. The tool bit holder of claim 4, wherein the detents are defined by locking balls provided on the tool bit holder body and corresponding annular recess provided in the stablizing sleeve. 8. The tool bit holder of claim 1, wherein the locking collar is radially displaceable between a locking position in which the collar prevents removal of the tool bit from the tool bit socket and a release position in which the collar allows removal of the tool bit from the tool bit socket. 9.
