Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Precision Clamping: High-grade 65Mn steel construction ensures secure, accurate holding of drill bits, end mills, and other workpieces, minimizing vibration and ensuring precise alignment during machining.
  • Adjustable Clamping: Radial slots allow customizable expansion/contraction to accommodate varying workpiece sizes, enabling versatile clamping for diverse machining tasks.

Key features

  • 1. Material Technology: Hardened 65Mn Steel Construction

    • With hardened 65Mn steel, you can achieve exceptional durability and resistance to deformation under high machining forces. This material outperforms standard steel in maintaining precision over repeated use*, ensuring long-term reliability in demanding applications.

  • 2. Interactive Design: Radial Slot Adjustment System

    • With precision-engineered radial slots, you can quickly adjust clamping sizes for different workpiece diameters without manual calibration, saving 30% more setup time than traditional chucks*. The slots also minimize vibration for smoother operations.

  • 3. Performance Parameters: Reduced Chatter & Enhanced Stability

    • With optimized radial slot geometry, you can reduce machining chatter by up to 25% compared to non-precision collets*, enabling higher-quality finishes and extended tool life. The flanged design ensures stable alignment during high-speed drilling or milling.

  • 4. Scenario Solutions: Commercial-Grade Durability

    • With a hardened steel body and precision engineering, you can handle continuous commercial use without compromising accuracy, unlike lower-grade collets prone to wear after prolonged operation*. Ideal for workshops and industrial settings.

  • 5. Certification Standards: CE Certified Safety & Compliance

    • With CE certification, you can ensure compliance with EU safety and quality standards, guaranteeing reliable performance and reduced risk of tool failure. This certification is absent in many competing products*.
