ER20 2 mm Collet Tool Holder
The ER20 2 mm Collet is a critical mechanical component engineered for high-precision tool holding in industrial machining processes, including CNC milling, turning, and specialized tool manufacturing. Designed to secure cylindrical shank cutting tools, this collet provides exceptional centering and clamping force even under high rotational speeds and dynamic loads.
The operating principle relies on the collet’s conical outer surface seating into the tool holder’s internal taper. As the collet nut is tightened, it applies axial force, compressing the collet radially. This ensures the flexible segments grip the tool shank with uniform pressure, minimizing runout and vibration. Reduced runout is essential for improving machining quality, optimizing surface finish, and extending the service life of cutting tools.
Key Technical Advantages:
- High Runout Precision: Engineered for tight tolerances to minimize deviation from the rotation axis, ensuring balanced load distribution and superior geometric accuracy.
- Secure and Stable Clamping: The optimized conical geometry guarantees absolute axial and radial stability, preventing tool slippage or vibration during aggressive machining operations.
- Universal Compatibility: Fully compliant with industrial standard ER20 specifications, allowing for seamless integration with a wide range of existing CNC tool holders and machinery.
- Durable Construction: Manufactured from high-quality alloy steel, precision heat-treated for wear resistance, and ground to micron-level accuracy.
