ER16 4 mm Collet Tool Holder

ER16 4 mm Collet Tool Holder

Industrial Automation Components | Superior Performance Series

The ER16 4 mm Collet is a high-precision engineering component essential for CNC milling, turning, and machining centers. It is designed to securely center and clamp 4 mm diameter cylindrical cutting tools. By minimizing runout (TIR) to micron levels, this collet absorbs vibrations, ensures uniform load distribution on cutting edges, and achieves exceptional surface finish and dimensional accuracy.

Technical Specifications and Durability

Manufactured from high-strength, elastic spring steel (65Mn or equivalent), this collet maintains its form and fatigue resistance even after repeated clamping cycles. It undergoes specialized heat treatment to reach a hardness range of HRC 44-48, providing outstanding resistance to wear, deformation, and corrosion. When used with a standard ER nut, it provides a secure, rigid grip necessary for high-RPM operations.

Key Advantages

• Ultra-Precise Runout Control: Engineered for minimal deviation, ensuring synchronized contact between the tool and workpiece, which extends tool life and improves surface Ra values.
• Maximum Torque Transmission: The optimized conical geometry provides high radial clamping force, preventing tool slippage under heavy cutting loads and increasing overall machining stability.
• Universal Compatibility: Complies with international DIN 6499 / ISO 15488 standards, ensuring seamless integration into existing industrial tool-holding systems.
