Feature：
1、Using high quality alloy steel 40CrMnTi forging, the material is metallographic dense, uniform and stable.
2、After carburizing, the outside of material is hardened, and the inside of material is still soft and has enough toughness. Therefore, Material has higher wear resistance and better toughness.
3、CNC on all critical surfaces including a pilotunder the flange of retention knob for full contact between tool holder's taper end and retention knob. Precision grinding pull stubs have higher surface finish and dimension accuracy.  The fitting accuracy is obviously higher than that of machine pull stubs, effectively reduces the error of  machine tool and cooperation, so as to improve the accuracy and stability of the connection and improves the precision of the machine tools and lengthens the service life
