ER32 3 mm Collet Tool Holder

The ER32 3 mm collet is a critical component for precision machining, designed to securely hold cylindrical shank cutting tools such as micro-mills, drills, reamers, and engraving bits in CNC machining centers, milling machines, and lathes. Engineered for high rigidity and minimal runout, this collet operates by converting axial clamping force from the collet nut into radial force, ensuring the tool is firmly gripped through elastic deformation.

Technical Specifications and Material Quality:
Manufactured from high-carbon alloy steel (SUJ2/100Cr6), this collet undergoes specialized heat treatment to achieve an optimal hardness range of HRC 44-48. This ensures excellent wear resistance and long-term performance under dynamic loads. Precision grinding of the internal and external conical surfaces provides micron-level accuracy, ensuring homogeneous contact and effective clamping force. It adheres to the DIN 6499 / ISO 15488 standard, offering seamless integration with various CNC tool holders.

Key Advantages:

• Superior Runout Accuracy (≤ 0.003 mm): Minimizes tool deviation, ensuring balanced cutting forces, extended tool life, and exceptional surface finish on workpieces.
• Optimal Rigidity and Vibration Damping: The robust design limits tool deflection and micro-movements, absorbing vibrations to enhance stability during high-speed operations.
• Wide Industrial Compatibility: Fully compliant with international standards, making it compatible with a vast range of BT, CAT, HSK, and SK tool holders.
