The Omega BT50 ER Collet Chuck (ER25) is a robust tool holder designed for BT50 spindle systems. It securely clamps ER25 cutting tools with a focus on stability and precision for a wide range of milling and drilling tasks. With a 160mm gauge length and Form AD/B mounting, it offers the right balance of reach, rigidity, and compatibility for demanding setups while maintaining smooth, balanced operation at speed.

Engineered for high-speed machining, it handles a 15,000–25,000 RPM range and delivers consistent clamping force. Its G2.5 and G6.3 precision ratings indicate excellent tool concentricity and minimal runout, translating into tighter tolerances, improved surface finishes, and fewer rework passes.

• Wide-speed capability (15,000–25,000 RPM): Enables a broad set of tools and applications to be used efficiently with a single holder, reducing setup time and increasing throughput.
• Exceptional concentricity and low runout: G2.5 and G6.3 ratings ensure accurate tool alignment for consistent hole sizes and smooth finishes.
• Secure, repeatable tool retention: BT50–ER25 interface provides reliable clamping under heavy cuts, minimizing downtime and extending tool life.

With this BT50 ER Collet Chuck, you gain a dependable, repeatable tool-holding solution that improves workflow, reduces rework, and delivers consistent results across production runs. Its precision and rugged design help you achieve tighter tolerances, smoother finishes, and longer tool life, making it a smart choice for shops, engineers, and technicians who demand dependable performance from their equipment.
