The BT30 Pull Stud Set (5 Pieces) is a precision-engineered collection of retention knobs designed for CNC machines using BT30 tool holders. Identified by its ISO standard designation MAS 403, these pull studs form an essential mechanical link between the machine spindle and the tool holder, ensuring secure and reliable clamping during machining operations.
Pull studs operate under extremely high clamping forces and spindle speeds. Therefore, strict requirements for accuracy, rigidity, and reliability must be met. Low-quality pull studs can reduce machining performance and pose serious safety risks. A broken pull stud may cause severe damage to the machine and workpiece and can even result in injury to operating personnel.
This BT30 pull stud set is manufactured from special high-strength alloy steel and is properly heat-treated to provide superior rigidity, wear resistance, and long service life. The set includes various degree angles and is available in with hole and without hole options to meet different CNC machine and coolant system requirements.
