The Omega Products ISO 7388/2-A Pull Studs are hollow, through-coolant pull studs designed for ISO 7388/2-A tool holders. Their through-coolant capability channels coolant directly through the center to the cutting zone, supporting efficient chip evacuation and consistent cooling during demanding machining operations. Without an O-ring, these pull studs maximize coolant flow and simplify maintenance in through-coolant systems. Precision-engineered to ISO standards, they ensure a reliable fit and stable performance with ISO 7388/2-A holders across a wide range of applications. Through-Coolant Flow Design: coolant travels through the hollow center to the cutting zone, improving chip evacuation, reducing heat, and helping achieve better surface finish and tool life. Hollow Construction with No O-Ring: optimized for through-coolant systems, maximizing coolant delivery while minimizing potential leakage points and simplifying maintenance. ISO40 Compatibility with ISO 7388/2-A Holders: precision-engineered to ISO standards for a dependable fit, consistent clamping force, and accurate tool positioning in demanding environments. Designed for reliability in everyday production, these pull studs help maintain repeatable tool performance, enhance cooling efficiency, and extend tool life. Their robust construction and exacting tolerances translate to faster setup, fewer interruptions, and more consistent results across projects.
