The HSK63A Shrink Fit Holder with Front Face Coolant is built for high-speed machining, delivering secure tool retention and precise alignment in demanding milling and drilling jobs. It’s a versatile choice for engineers, shop-floor technicians, and hobbyists who demand repeatable results and fast, reliable tool changes.

Featuring an integrated front-face coolant system, it cools the cutting edge directly where it matters, helping maintain cutting performance and extending tool life. With a G2.5 interface, 120 mm gauge length, and a 3 mm clamping diameter, this holder is optimized for up to 25,000 RPM in tough, high-speed applications.

• Exceptional clamping strength and minimal runout: Shrink-fit retention provides rigid, stable tool positioning at speed for consistent tolerances and improved surface finish.
• Integrated front-face coolant system: Direct cooling at the cutting edge enhances heat management, reduces thermal growth, and extends tool life for longer production runs.
• High-speed readiness and precise geometry: Engineered for up to 25,000 RPM with a 3 mm clamping diameter and 120 mm gauge length, delivering reliable, repeatable performance in demanding machining tasks.

By combining secure retention, efficient cooling, and high-speed capability, this holder helps you reduce downtime, minimize tool changes, and maintain consistent part quality. It supports smoother workflows, longer tool life, and reliable results across challenging manufacturing environments.
