扇形软爪，钢制

Full grip jaws made of steel are used for machining sensitive workpieces. The large bearing surface ensures that clamping forces are evenly distributed over the workpiece area, thereby reducing deformation of the workpiece.
The delivery unit comprises 1 set = 3 pieces. For top jaw SWB-M/4, 1 set = 4 pieces for a 4-jaw chuck.
