KURATA TOOLS - Leading Manufacturer of High Precision Clamping Systems. Discover How We Help
KURATA Tools specializes in the R&D, production, and sales of high-precision clamping systems for CNC machine tools.
The BT40 Hydraulic Chuck is a premium solution for high-precision CNC machining, offering exceptional accuracy and stability. Unlike conventional mechanical collet chucks, the Hydraulic Clamping System uses hydraulic pressure to provide uniform clamping around the tool shank. This results in superior runout accuracy, vibration reduction, and improved tool life, making it an ideal choice for high-speed finishing and delicate machining tasks.
Our BT Hydraulic Tool Holder series is designed for both roughing and finishing applications in industries such as aerospace, automotive, mold & die, and precision engineering. Combined with a complete Hydraulic Tooling System, the BT40 chuck ensures faster tool changes and consistent performance.
Ultra-High Accuracy: Runout ≤ 3 μm for precision machining.
Quick Clamping: Easy tightening with an Allen key; no heating or shrinking required.
Excellent Vibration Damping: Hydraulic oil absorbs micro-vibrations, improving surface finish.
Dynamic Balance: Ideal for high-speed CNC machining up to 25,000 RPM.
Durable Material: Made from hardened alloy steel for long-term performance.
CNC Machining Centers – High-speed milling and drilling.
Mold & Die Manufacturing – Precision cavity cutting.
Aerospace Components – Tight-tolerance parts machining.
Automotive Industry – Complex and high-precision parts.
Medical Device Manufacturing – Delicate materials requiring stable clamping.

Customized sizes and lengths available on request.
Hydraulic vs Shrink Fit: Hydraulic chucks allow easy tool changes without special heating equipment, while shrink fit provides maximum rigidity but requires additional machines.
Hydraulic vs ER Collet Chucks: Hydraulic offers higher precision and better vibration control.
Hydraulic vs Milling Chuck: Hydraulic is best for finishing and semi-finishing; milling chucks are better for heavy-duty roughing.
