A machine tool bit holder providing a stable connection between a machine and a tool bit being used to perform machining operations on a work piece. The holder for the tool bit is of simple construction and has a large contact area relative to a tool bit size and a holder size between the holder and the tool bit, and the holder is configured so that the tool bit can be easily mounted into and dismounted from the holder. The holder allows different shapes or configurations of tool bits, such as an angle between the holder and the tool bit, and tool bits that are substantially rectangular as well as substantially round in cross-section.
