The Omega BT50 ER Collet Chuck is a precision tool holder built for BT50 spindle systems. It securely clamps cutting tools to deliver stable, accurate performance across a wide range of milling and drilling tasks.

Featuring a 100 mm gauge length and Form AD/B, this ER collet chuck is engineered for balanced rigidity and repeatable seating. The G2.5 and G6.3 precision ratings indicate excellent tool concentricity and minimal runout, helping you achieve tighter tolerances and smoother surface finishes even at speeds up to 25,000 RPM.

• High-precision concentricity (G2.5 / G6.3): G2.5 and G6.3 ratings reflect tight runout and consistent tool alignment, delivering repeatable tolerances and smoother finishes with every cut.
• Wide RPM range (15,000–25,000 RPM): Supports a broad set of cutting conditions, enabling versatile tool usage within a single chuck for many machining tasks.
• 100 mm gauge length, Form AD/B: Fixed gauge length provides stable seating and predictable clamping in BT50 spindles, improving setup repeatability and reliability.

With secure tool clamping, precise concentricity, and robust BT50 compatibility, this ER collet chuck helps maintain consistent quality, reduce setup time, and streamline tool changes—supporting productive milling and drilling workflows in shops and production environments.
