The Omega Products BT40 ER Collet Chuck provides machinists with a dependable tool holder for BT40 spindle CNC machines that demand both reach and high-speed stability. Built for ER25 collets, it supports precision cutting operations where extended gauge length and low runout are essential.

• Taper and Collet System: BT40 shank with ER25 collet capacity for secure tool clamping across a wide range of end mills and drills.
• Balance and Speed Rating: Dynamically balanced to G2.5 at 25,000 RPM, minimizing vibration during high-speed machining.
• Gauge Length: 200 mm extended projection length for improved access to deep cavities and complex contours without requiring tool extensions.
• Coolant Delivery: Form AD/B design allows through-tool coolant flow to maintain consistent cutting temperatures and chip evacuation.

This collet chuck helps reduce tool deflection and surface finish issues on parts that require long-reach operations, allowing operators to maintain tighter tolerances and extend tool life in production milling and drilling applications.
