Meet the Omega BT40 ER Collet Chuck in Mini Type — a compact, high-precision tool holder designed for BT40 spindles and ER16 tooling. Its lightweight, balanced construction minimizes tool overhang, delivering consistently accurate cuts and superior surface finishes at high speeds.
- BT40 Mini Type Design: A compact, lightweight chassis that improves balance and reduces tool overhang for cleaner cuts and steadier performance.
- ER16 Collet System: Quick, secure tool changes with reliable clamping to hold small-diameter tooling with consistent accuracy.
- High-Speed Capability: Rated up to 20,000 RPM, making it suitable for fast milling, drilling, and finishing operations.
- Precision Runout: G2.5 tolerance to maintain tight tool concentricity and minimize runout during high-speed machining.
- Gauge Length: 70 mm gauge length (Form AD/B) for predictable reach and compatibility with standard tooling setups.
- Rugged Construction: Precision-machined body built to withstand frequent tool changes and long production runs without compromise.
This combination delivers tighter tolerances, smoother finishes, and longer tool life by maintaining concentricity and reducing chatter. The quick-change ER collet system helps minimize non-cut time, boosting throughput in CNC milling and drilling applications. Ideal for precision-work where small-diameter tooling, repeatable results, and reliable performance at up to 20,000 RPM are essential.
