Description
Keep milling tools firmly supported in your BT40 spindle with this Omega ER32 collet chuck. Its 70 mm gauge length and high-speed rating suit production work where repeatable tool positioning and steady cutting matter.
Use it for operations such as milling aluminum components, machining pockets in steel, or changing tools across a production run. The ER32 interface works with the standard ER32 collet system, giving you flexibility across compatible tooling.
- BT40 spindle fit: Mounts directly on BT40 spindle systems for integration with existing setups.
- ER32 toolholding: Supports standard ER32 collets for broad tooling compatibility and repeatable tool changes.
- Speed and precision: Rated at 20,000 RPM with G2.5 precision for high-speed machining applications.
- 70 mm gauge length: Form AD design supports stable tool positioning during milling.
- Coolant compatibility: Works with through-spindle or external coolant to support chip evacuation.
- Rigid, hardened construction: Built for demanding production use, with rigidity intended to help reduce chatter at high speeds.
Secure clamping and low runout support accurate cuts, helping you pursue a cleaner surface finish and longer tool life. This chuck is a practical choice for production setups that need consistent performance across milling jobs.
