Set Of 5 CT40 / CAT40 Pull Stud | Multiple Degree | With Hole / Without Hole | CNC Tool Holder

The Set of 5 CAT / CT40 Pull Stud is a precision-engineered retention knob designed for CNC machines using CAT40 tool holders. Known internationally by its ISO standard name MAS 403, this pull stud forms a vital mechanical link between the machine spindle and the cutting tool.

Pull studs are subjected to extreme forces during high-speed and heavy-duty machining. Therefore, strict requirements for accuracy, rigidity, and reliability must be met. Low-quality pull studs can reduce machine performance and create serious safety hazards. A failed or broken pull stud may cause severe damage to the machine and workpiece and may even lead to injury of operating personnel.

Our CAT/CT40 Pull Studs are manufactured from special high-strength alloy steel and are properly heat-treated to ensure maximum rigidity, wear resistance, and long service life. These pull studs are available in various degree angles and in with hole and without hole versions to suit different CNC machine designs and coolant requirements.
