Learn more about Klarna
Description
The Omega Products Pull Stud BT (MAS) Hollow with O Ring is a through-coolant pull stud designed specifically for BT (MAS) tool holders. Its hollow center and O-ring seal ensure coolant can reach the cutting area, improving cooling, chip evacuation, and overall machining efficiency in high-speed operations.
- Through-Coolant Hollow Design: Delivers coolant directly to the cutting zone via a hollow bore, enhancing cooling and chip evacuation to boost productivity and extend tool life.
- O‑Ring Seal for Leakage Prevention: Provides a reliable, tight seal around the hollow bore to maintain coolant pressure and prevent leaks during demanding machining cycles.
- Precision 45° BT MAS Interface (ISO 50): Enables secure, stable mounting with precise threading for high-speed, accurate toolholding compatible with standard BT MAS fittings.
Designed for consistent performance, this pull stud supports reliable tool retention at high RPMs while maximizing through‑coolant efficiency. Its durable construction and exacting tolerances help minimize downtime, maintain alignment, and deliver repeatable results across demanding milling and turning applications.
