ER20 6 mm Collet Tool Holder
Industrial Automation Components | Premium Performance Series
Product Overview
The ER20 6 mm Collet Tool Holder is a critical component engineered for high-precision industrial automation and machining processes. It ensures that cutting tools are secured to the spindle with maximum rigidity and accuracy. This collet is specifically developed to provide stability against radial and axial forces during CNC milling, turning, and engraving. By minimizing runout, it directly enhances surface finish, dimensional tolerances, and tool longevity. Designed according to the DIN 6499 standard, the ER20 series is a globally recognized solution for reliable tool clamping.
This collet securely grips 6 mm nominal diameter cutting tools with a clamping range of 5.5 mm to 6.0 mm, preventing slippage or vibration even at high RPMs. For optimal performance, it is recommended to use a calibrated torque wrench with the collet nut to ensure precise clamping force, which can achieve runout values as low as 3 microns. Manufactured from high-quality alloy tool steel and subjected to specialized heat treatment, this collet offers exceptional wear resistance and mechanical strength. Its modular design ensures seamless integration with existing ER20 collet chucks and nut holders.
Key Advantages
- High Runout Precision: Offers up to 3-micron runout accuracy, essential for high-tolerance applications such as mold making, medical part production, and aerospace engineering.
- Secure Clamping Mechanism: Ensures the tool remains stable under high-speed and heavy-load conditions, reducing harmonic vibrations and increasing production efficiency.
- Versatile Compatibility: Compatible with a wide range of cutting tools including carbide end mills, drills, and engraving bits. Its modularity allows for quick tool changes and easy integration into existing CNC setups.
