The HSK63A-SF03-80K Shrink Fit Chuck is engineered for high-speed and high-precision machining applications where exceptional accuracy, rigidity, and reliability are essential. Manufactured from premium alloy steel and precision ground to tight tolerances, it ensures excellent concentricity, secure tool clamping, and long-term dimensional stability.
Designed with a 4.5° taper bore and through-coolant (AD) system, the holder delivers coolant directly to the cutting zone, improving heat dissipation, chip evacuation, and machining efficiency. With a runout accuracy of ≤0.003 mm and dynamic balancing to G2.5 at 25,000 RPM, it provides stable performance even under demanding high-speed machining conditions.
The HSK63A shrink fit chuck is suitable for solid carbide end mills, drills, reamers, and other precision cutting tools, making it an ideal solution for modern CNC machining centers.
