A vacuum system and apparatus extracts metal chips and cuttings away from the cutting area of a sawing machine. The system and apparatus is located on the previously cut surface end of the saw and includes rotatable bracketry to engage and disengage a vacuum nozzle from the end of a cut piece to extract metal chips and cuttings from the inside of hollow metal stock as the stock is being cut. Rotation of the bracketry is actuated by means of an electronic controller or other control circuitry.
