ER16 6 mm Collet Tool Holder
The ER16 6 mm Collet is a critical interface component for modern CNC machining centers and machine tools, designed to secure cutting tools to the spindle with high precision and rigidity. This collet is specifically engineered to maintain the position of cylindrical shank tools—such as drills, end mills, and reamers—against radial and axial forces, ensuring minimal run-out during operation. By perfectly aligning the tool’s center axis with the spindle axis, it ensures uniform load distribution, extends tool life, and minimizes vibrations that affect surface quality and geometric tolerances.
Manufactured from high-quality alloy steel, this ER16 6 mm collet undergoes rigorous heat treatment and precision grinding to achieve optimal hardness, wear resistance, and dimensional stability. Its conical design and flexible segments provide uniform clamping force when tightened with the collet nut. The ER series standardization allows for easy integration into existing ER-type tool holders, offering versatile use across different machines and applications.
Key Advantages:
- High Run-out Control: Minimizes deviation from the rotation axis, ensuring balanced contact and reduced localized tool wear.
- Superior Clamping Rigidity: Provides high radial clamping force, preventing tool slippage or axial movement even under aggressive cutting conditions.
- Operational Flexibility: Designed according to DIN 6499 standards, ensuring full compatibility with a wide range of CNC and conventional machine tools.
- Wide Application Range: Ideal for industries requiring high precision, including aerospace, medical, mold making, and defense.
