The Omega Products Mazak Pull Stud is a hollow pull stud designed for Mazak machines, featuring a 44.1 mm length and an ISO40 interface. It is offered without an O-Ring and is intended for through-coolant applications, providing a secure and reliable connection between tool holders and cutting tools. The hollow design enables coolant to flow through the stud directly to the cutting edge, delivering effective cooling and lubrication during demanding machining operations. Built with precision engineering and high-quality construction, these pull studs resist wear and maintain consistent performance in challenging environments. Through-Coolant Hollow Design: Allows coolant to travel through the stud to the tool, improving cooling and lubrication for steadier cutting performance and tool life. ISO40 Mazak Compatibility: Optimized for Mazak tool holders, ensuring a secure, accurate fit and reliable clamping during heavy-duty machining. No O‑Ring, Durable Construction: Hollow, precision-machined design without an O‑Ring minimizes leak points and supports durable, long-term reliability in tough shop conditions. Choosing this pull stud helps you maintain consistent tool seating, improves cooling efficiency through the through-coolant path, and supports faster setups with reliable, repeatable results across Mazak-compatible tooling. It’s a dependable component for high-precision milling and drilling operations where stable clamping and effective cooling are essential.
