ER11 Spring Collet Set 12Pcs High Accuracy for CNC Machine

1 Excellent Material: Collet chuck is made of alloy steel with high strength, high toughness, wear resistance, corrosion resistance and high temperature resistance. 2 Strong Performance: After heat treatment and cold drawing hardening, the collect set has relatively high strength, and has a certain degree of flexibility and plasticity. Under the same surface state and complete quenching, the fatigue limit is equivalent to that of a multicolor alloy spring. 3 High Accuracy: Collet chuck adopts internal and external fine grinding treatment, which makes the slot position smoother and has higher accuracy. Provide you with a better work experience. 4 Concave Design: The concave design in front of the collet cone can effectively prevent dust from entering during work and avoid affecting mechanical work. 5 Wide Application: Collet chuck is used in a wide range of applications and perfect for CNC milling lathe tool and work holding engraving machine.
