1、40cr Material: The tool bar is made of 40cr material, which has high hardness, strong durability, stable performance and good working performance. 2、Surface Coating: The surface of the tool holder adopts a new coating process, which has good oxidation resistance and high temperature resistance, which is more durable and increases the service life of the tool holder. 3、Finishing Tool Holder: The high strength machining of the tool holder makes it strong in shock resistance, higher in work efficiency and longer in service life. 4、Superior Performance: The shank is finely crafted, compact in appearance and stable in performance, ensuring durability and stability. 5、Wide Application: Milling tool bars are mainly used in CNC machining centers and CNC engraving machines. It can also be installed on ordinary milling machines to process some harder and less complex heat treated materials.
