Learn more about Klarna
Description
The Omega Products Pull Stud BT (MAS) Hollow with O Ring Through Coolant is a specialized fastening solution designed for BT (MAS) tool holders used in machining. Its hollow core and O-ring seal enable coolant to pass through the center of the stud, delivering cooling exactly where the cutting action happens while keeping leaks at bay. This arrangement supports efficient chip evacuation and more consistent cutting performance across demanding operations.
- Through-Coolant Hollow Design: Delivers coolant directly through the stud to the cutting zone, improving temperature control and chip removal for smoother, more reliable milling and turning.
- O‑ring Seal for Leak-Free Performance: Integrates a resilient seal that maintains a tight interface, ensuring steady coolant flow and reducing maintenance or leakage concerns.
- BT (MAS) 90° ISO 50 Compatibility: Combines precise threading and robust construction to securely fasten the tool holder to the spindle with stable, high-speed performance and dependable alignment.
This pull stud helps you maintain consistent coolant delivery, which extends tool life, reduces downtime, and enhances surface finish and accuracy across a range of through-coolant applications. It’s a reliable, straightforward upgrade for shops prioritizing productivity and repeatable results.
