Omega Products BT40 Shrink Fit Chucks with Front Face Coolant - G2.5 - 25,000RPM - 16mm - 90mm

The Omega BT40 Shrink Fit Chuck with Front Face Coolant is a robust toolholding solution built for BT40 machining centers that demand rigidity, repeatable accuracy, and effective cooling at speed. Designed around a shrink-fit retention system and integrated front coolant channels, it keeps cutting tools cool and secure, helping you maintain precise results during high-speed operations.

This chuck is engineered for reliability in demanding environments and complies with BT MAS403 (JIS 6339) standards, Form AD/B. It is balanced to G2.5 at 25,000 RPM and specified for a 16mm size with a 90mm form factor, ensuring compatibility with a wide range of BT40 machines.

• Integrated Front-Face Coolant Channels: Direct cooling at the cutting edge during high-speed machining helps maintain accuracy, reduces heat-related wear, and extends tool life.
• BT40 Shrink-Fit with Precise 4.5° Seating: Provides stable, uniform clamping and a precise seating geometry for repeatable performance in demanding, fast-cutting applications.
• G2.5 Balance at 25,000 RPM & Standards Compliance: Delivers smooth, low-vibration operation at high speeds while conforming to Form AD/B and BT MAS403 (JIS 6339) for reliable interchangeability with BT40 tooling.

Together, these features translate to faster setups, consistent clamping quality, and improved finish when challenging materials are machined. The front-face coolant keeps heat under control, helping you extend tool life and reduce rework, while the strict standards compliance and proven balance support dependable performance across your BT40 tooling ecosystem.
