Custom-fit complex component geometries and achieve distortion-free concentric workholding with industrial-grade Jaws for Centring Vices (soft machinable jaw blanks / self-centering vice jaw inserts). Designed specifically for high-precision centring and 5-axis vices, these machinable steel jaw blocks allow programmers and machinists to mill custom pocket contours matching exact part profiles. Engineered for rapid, repeatable attachment onto base vice carriers, they provide maximum contact surface area, superior concentric clamping stability, and vibration-free holding for delicate or thin-walled workpieces during multi-axis CNC operations.
