NT Retention Knob Pull Stud With Improved Surface Hardness And Wear-Resistance For CNC Tool Holder


NT retention knob Pull Stud,There are three types of NT pull stud, NT30, NT40, and NT50,, which are mainly used in NT CNC tool holder. NT30 tool holder with NT30 pull stud, NT40 tool holder with NT40 pull stud, NT50 tool holder with NT50 pull stud. The pull stud is made of high quality steel 20CrMnTi, with HRC hardness ranging from 48 degrees to 56 degrees according to different uses. The overall compact and stable, special rust-proof material, overall carburizing treatment, compared with the ordinary pull nail increased by 1 times the wear resistance and tensile resistance. The overall performance is better. Accuracy: less than 0.005mm.CNC pull stud manufacturer, pull stud specifiCATEEions and models, can be customized according to customer requirements, good quality, excellent price, welcome to order wholesale!


NT retention knob Pull Stud Features:
1. Wear-resisting and Surface hardness improved.
2. Precision stability,good cleaning.
3. Smooth surface,beautiful appearance.





1. Material: 20CrMnTi

2. the type: DIN2080 pull stud

3. hardness: 56-60HRC

4. High-quality low-carbon alloy just after carburizing processing thread

5.handle high hardness (wear-resistant, long service life)

6.Thread more accurate and slightly lower hardness (to protect the handle thread)

7.The lowest core hardness (impact), suitable for high-end tool holder8. Internal quality, anti-rust effect is good, widely used abroad processing cryogenic treatment and thermal aging can reduce the residual stress, improve the durability and stability

retention knob is a critical component of a tool holder used in machining operations. It is designed to securely hold the cutting tool in place within the tool holder, ensuring that it does not come loose during operation. The NT retention knob is a specific type of retention knob that is used with NT tool holders, which are commonly used in milling machines. The NT retention knob is designed to provide a strong and reliable connection between the tool holder and cutting tool, helping to maximize machining accuracy and efficiency. It is important to regularly inspect and replace retention knobs as needed to ensure safe and effective operation of the machine.
