10x CAT 40 5/8-11 60° Pull Studs - Retention Knobs For Milltronic Kira CAT40 CNC Machines

About This Product

CNC machinists and shop owners - if you're running Milltronic, Kira, or other CAT40 CNC machines, these pull studs are essential maintenance items you need to keep on hand.

This pack gives you 10 identical CAT 40 retention knobs with the 5/8-11 thread and 60° angle that specifically fits Milltronic and similar CAT40 toolholders. Why do these matter?

They're the critical interface between your toolholder and the CNC machine's automatic tool changer - without proper retention knobs, your tool changing reliability goes out the window. The 60° angle is precision-machined to ensure secure engagement in the spindle, preventing tool slippage during high-speed operations. The 5/8-11 thread screws securely into your CAT40 toolholders, and having multiple spares means you can quickly replace worn studs without machine downtime. Worn or damaged pull studs can cause all sorts of problems - from tool holder slippage to complete tool changer failures. Having fresh replacements ready to go is just smart shop practice. These are manufactured to proper specifications to ensure compatibility and reliability.

Whether you're doing preventive maintenance or need replacements for specific toolholders, keeping a supply of these studs on hand saves you from production delays.

For smooth, reliable tool changes and peace of mind during production runs, these CAT40 retention knobs are small investments that protect your much larger machine investments.
