ER20 5 mm Collet Tool Holder
The ER20 5 mm collet is a critical mechanical component engineered for high-precision tool holding in modern machining processes. It ensures that cylindrical shank cutting tools—such as drills, end mills, reamers, and taps—are centered with millimeter accuracy and held securely against machining forces. Its conical design allows for uniform radial clamping when tightened with a collet nut, effectively minimizing axial and radial runout and absorbing vibrations during operation.
Key Features and Benefits:
- Precision Runout Control: Minimizes runout to ensure consistent contact between the cutting edge and the workpiece, extending tool life and improving surface finish.
- Uniform Clamping Force: Distributes torque evenly around the tool shank, preventing localized stress and ensuring stability during aggressive machining parameters.
- Standardized Compatibility: Manufactured according to DIN 6499 / ISO 15488 standards, ensuring seamless integration with a wide range of CNC machining centers, lathes, and automated systems.
- Durable Construction: Made from high-quality alloy steel with precision-ground surfaces, offering excellent hardness, toughness, and wear resistance for demanding industrial environments.
