12Pcs Collet Chuck High Accuracy ER11 Spring Collet Set For CNC Engraving Machin

Feature: \n 1. Excellent Material: Collet chuck is made of alloy steel with high strength, high toughness, wear resistance, corrosion resistance and high temperature resistance.\n2. 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.\n3. High Accuracy: Collet chuck adopts internal and external fine treatment, which makes the slot position smoother and has higher accuracy. Provide you with a better work experience.\n4. Concave Design: The concave design in front of the collet cone can effectively prevent dust from entering during work and avoid affecting mechanical work.\n5. Wide Application: Collet chuck is used in a wide range of applications and perfect for CNC milling lathe tool and work holding engraving machine. \n\nSpecification: \n\nItem:
