SK40 pull stud is a type of tool holder used in machine tool appliCATEEions. It is commonly used in milling machines and machining centers. The pull stud serves as a connection between the tool holder and the machine spindle, ensuring a secure and accurate grip on the cutting tool.

The SK40 pull stud is designed to fit into a corresponding spindle taper, typically a BT40 or CATEE40 spindle. It features a threaded end that connects to the tool holder, and a tapered end that fits into the spindle taper. The pull stud is tightened using a retention knob or drawbar, which pulls the tool holder into the spindle taper, creating a strong and rigid connection.

The SK40 pull stud is known for its high clamping force and precision, making it suitable for heavy-duty machining operations. It is also compatible with a wide range of tool holders and cutting tools, allowing for versatility in machining appliCATEEions.

Overall, the SK40 pull stud is a critical component in machine tool setups, providing a reliable and secure connection between the tool holder and the machine spindle.
