Omega Products HSK63A Shrink Fit Holders With Front Face Coolant - G2.5 - 25,000RPM - 4mm Clamping Diameter - 80mm Gauge Length

Omega HSK63A Shrink Fit Holder with Front Face Coolant is a precision tool holder designed for high-speed milling and demanding machining tasks. It uses shrink-fit clamping to grip small-diameter tools securely, delivering superb rigidity and minimal runout for tight tolerances. With a front-face coolant channel, this holder actively cools the cutting edge during high-speed operations, helping you sustain speeds up to 25,000 RPM while extending tool life. The compact 4 mm clamping diameter and 80 mm gauge length balance reach with stability for a wide range of tools and applications.

• Front Face Coolant for Efficient Heat Management: Directs coolant to the cutting edge through the front face, reducing heat buildup, controlling tool temperature, and boosting tool life during high-speed milling.
• Shrink-Fit Clamping for Ultra-Precise Seating: Provides tight, repeatable tool grip with minimal runout, improving tolerance consistency and yielding smoother surface finishes on demanding cuts.
• High-Speed Ready with Stable 4 mm Clamping and 80 mm Gauge Length: Optimized for up to 25,000 RPM, offering secure retention of small-diameter tooling while maintaining rigidity and predictable performance thanks to the 80 mm gauge length.

With this HSK63A shrunk-fit holder, you can expect reliable, repeatable results across a range of materials and milling scenarios. The integrated coolant, precise seating, and robust construction reduce downtime, lower rework, and help you achieve consistent finishes and productivity gains in your machining workflow.
