CNC ER Nuts Clamp Nut for tool holder

CNC ER Nuts Clamp Nut for TOOL HOLDER ,Er Nut for Tool Holder Materials 42Crmo; 20CrMnTi,The self-locking function of the barrel clamp ensures that the barrel clamp will not fall off during installation. Specially designed for high-speed machinery, good balance. The special anti-corrosion treatment reduces the friction between the clamp and the nut, greatly improves the clamping force, and has the ability to block pollutants.
