Description
The Omega DV40 ER Collet Chuck ER50 (100mm gauge length, Form AD/B) is a high-speed toolholding solution designed for DV40 spindle systems. Built to DIN69871 standards, it plugs into standard DV40 machines and covers a wide 15,000–25,000 RPM range, making it suitable for a broad mix of drilling, milling, and finishing tasks. The robust design supports demanding shop environments while maintaining accurate tool seating and repeatable results.
Users can choose between precision balance ratings G2.5 or G6.3 to match their accuracy and vibration requirements, ensuring stable performance across applications. The ER collet system delivers excellent gripping force and concentricity, keeping tools securely centered even at high speeds for consistent finishes and longer tool life.
- Wide speed range for versatile machining: 15,000–25,000 RPM enables efficient drilling, milling, and finishing with a single chuck, reducing tool changes and cycle times while maintaining precision.
- DIN69871 compatibility with DV40 spindles and balance options: DIN69871 standard ensures easy integration with DV40 machines; choose G2.5 or G6.3 balance to optimize accuracy and vibration control, with a 100mm gauge length for stable seating.
- ER collet system for secure grip and concentricity: Provides strong holding power and tight concentricity, minimizing runout and delivering reliable tool retention at high speeds for better surface quality.
This toolholder delivers reliable, repeatable performance across a range of operations, helping you streamline setup, reduce downtime, and achieve consistent results. Its precise balance options, DIN69871 compatibility, and robust ER gripping ensure confidence in tool performance from first cut to final pass.
