The Omega BT40 Power Milling Chuck is a reliable toolholding solution designed for milling operations that demand speed, precision, and repeatable results. It’s ideal for engineers, machinists, buyers, tradespeople, and hobbyists who need secure end-mill retention on BT40 spindles to power through demanding tasks with confidence.

With a 12,000 RPM maximum speed, SC32 interface, and a G6.3 precision rating, this chuck minimizes runout and ensures precise tool positioning. The result is superior surface finish and tight part tolerances, even at higher feed rates, backed by robust materials and sturdy construction that stand up to high-speed milling.

• High-speed milling up to 12,000 RPM: Enables fast material removal and efficient production while maintaining control and accuracy.
• G6.3 precision for minimal runout: Delivers consistent tool alignment and repeatable results, improving surface quality and dimensional accuracy.
• 105 mm gauge length for versatile reach: Provides stable, predictable tool projection and broad compatibility with a wide range of end mills and setups.

In everyday use, this chuck helps you streamline workflows by delivering secure clamping, reliable performance, and durable construction that withstands the rigors of high-speed milling. It supports consistent results, reduces setup time, and gives you the confidence to tackle precision prototypes or demanding production runs with less rework and more predictable outcomes.
