4.1mm A20 Collet Chuck with Rubber Sleeve

This 4.1mm A20 collet chuck with rubber sleeve is an innovative all-in-one toolholder solution designed for precision CNC machining. It combines a high-precision ER-20 collet chuck with a dedicated 4.1mm collet, protected by a robust external rubber sleeve. This design not only ensures excellent clamping force and concentricity for 4.1mm tools but also effectively prevents the ingress of contaminants such as chips, coolant, and dust. In demanding, high-productivity environments, it is ideal for extending tool life, maintaining performance stability, and protecting the machine tool spindle interface.
