ER20 Collet Nut

The ER20 Collet Nut is a critical mechanical component designed for industrial automation systems and CNC machining centers. It ensures that cutting tools are secured to the spindle or tool holder with high precision, stability, and dynamic balance. This nut is compatible with standard ER20 collets (DIN 6499/ISO 15488), providing a secure axial and radial hold.

Key Features:

• High Precision and Low Runout: Engineered to minimize runout, ensuring the tool remains perfectly aligned with the spindle axis. This reduces vibration, improves surface finish, and extends tool life.
• Dynamic Balance: Optimized for high-speed operations, supporting stable performance even at high RPMs.
• Durable Construction: Manufactured from high-strength alloy steel, treated with specialized heat processes to withstand repetitive tightening cycles, high radial loads, and wear.
• Standard Compatibility: Features M25x1.5 threading, making it fully compatible with standard ER20 collet systems.
