Abstract: A pneumatic tool lock integral to the structure of a pneumatic tool and adapted to replace the existing male nipple component of the pneumatic tool is provided. The pneumatic tool lock includes an outer housing adapted to provide access to inner components of the pneumatic tool lock, the outer housing having a first end for securely mating with the pneumatic tool and a second end for coupling with a fluid source. An inner passageway within the outer housing provides a means for fluid to flow through from the fluid source to the pneumatic tool. A key operated lock mounted on the outer housing is displaceable between a first open position and a second closed position. A needle valve attached to the key operated lock disengageably mates with a channel extending between the inner passageway and the outer housing so as to block and un-block fluid flow into the inner passageway.
