Four-jaw chuck

  • Holding and clamping
  • Four-jaw chuck

Standard chucks usually clamp round or regularly shaped workpieces with three or six edges in three jaws. Unlike a three-jaw chuck, four-jaw chucks can be used to clamp accurately shaped round workpieces and workpieces with four or eight edges. Four-jaw chucks are used if the workpiece to be fixed is round or has four or eight edges. The workpiece is fixed with four jaws.
