Vacuum Quenched: The collet chuck holder has been vacuum quenched, has high hardness, strong toughness, good fatigue, impact and load resistance
Good Structural Rigidity: The milling shank holder is integrated formed, has good structural rigidity, the pressure is dispersed on the precise needle roller of the cage during use, suitable for large cutting amount processing
Connection Protective: The collet chuck holder is fully ground as a whole, effectively protecting the connection of the taper hole of the power head
Fine Grinding Processed: The external of the holder is brightly ground for beautiful and elegant appearance, the shank hole is fine grinding processed, with high centering accuracy
Wear Resistance and Stable: The mill tool holder is made of 40cr alloy steel, has better wear resistance and good stability
