BT-B Pull Stud for Tool Spindle, O-ring without Central Coolant
Brief introduction
High precision CNC milling lathe BT pull stud, tool stud.Pull studs of minor quality not only decrease the performance of the machine,they are even a safety risk.
A breaking pull stud might cause severe damage on machine and workpiece and even injuries on persons.
● Material: 20CrMnTi;
● Carburization depth:> 0.8;
● Hardness: 54-57HRC;
● Surface "green" special coating treatment, improve the surface hardness, wear resistance, improve cleanliness, more stable accuracy, the surface is more smooth, rust, better corrosion resistance, feel more comfortable and more beautiful appearance.
● Thread and other parts of the lower hardness: 35 ± 5HRC, (protection handle thread, the core hardness can withstand shock);
● Cryogenic treatment and heat aging treatment can reduce the residual stress, improve durability and accuracy of stability;
Type
BT-A: Central coolant without O-ring
BT-B: O-ring without central coolant
Other Model:
BT pull stud, SK pull stud, ISO7388 Pull stud, CATEE pull stud, Mazak Pull Stud, MTB Pull Stud, NT pull stud
Pull stud is mainly used for connet the tool spindle and tool holder
Products advantages
1. After heat treatment, and then quenching, cleaning, tempering, pull the nail out hard, not easy to fracture.
2. the use of flexible steel material.
3. BT conical shell cutter shank: 30, 50, 40
4. suitable milling cutter: 13mm-50mm
5. Precision is less than 0.01mm balance 8000rpm. High accuracy can also be made according to your requirements. (g6.3/12000rpm, G2.5 / 20000) 48-55hrc hardness.
6. suitable for pulling the stub with the milling cutter disk is also required.

Retention knobs are used in machine tool appliCATEEions to securely hold tool holders or collets in place. They are typically made of high-strength steel and feature a threaded shank that screws into the spindle of the machine tool.
BT30, BT40, and BT50 are different sizes of retention knobs that correspond to the respective sizes of the tool holders or collets they are designed to work with.
- BT30 retention knobs are used with BT30 tool holders or collets, which have a smaller diameter and are commonly used in lighter-duty milling machines or machining centers.
- BT40 retention knobs are used with BT40 tool holders or collets, which have a larger diameter and are commonly used in medium-duty milling machines or machining centers.
- BT50 retention knobs are used with BT50 tool holders or collets, which have an even larger diameter and are commonly used in heavy-duty milling machines or machining centers.
The retention knob plays a critical role in maintaining the accuracy and stability of the tool holder or collet during machining operations. It ensures that the tool holder or collet remains securely locked in place, preventing any movement or slippage that could affect the precision of the machining process.
It is important to use the correct size and type of retention knob for your specific machine tool and tool holder or collet to ensure proper functionality and safety.
