A pneumatic collet control system has a pneumatic cylinder subassembly with an internal shuttle subassembly with a central cylinder portion having an internal surface and a plurality of passageway holes on opposite ends of the cylinder communicating with the internal surface. The internal shuttle subassembly having a ram and a piston. A collet arm coupler is threadedly received into the external end of the ram. A valve body subassembly has a pair of valves and a pair of passageways for the valves for allowing and controlling the flow of actuating fluid into the cylinder with the passageways aligning with and coupling to the passageway holes of the cylinder. A central actuating fluid passageway connects with the two valves. A rotatable flow direction arm with a pivotable operator controlled handle controls the flow of actuating fluid into the cylinder.
