Product Introduction

Engineered for high-speed CNC machining, our industrial-grade Heat Shrink Tool Holders deliver exceptional rigidity, balance, and precision for the most demanding manufacturing environments. These high-performance tooling components are designed to maximize your operational efficiency, improve workpiece surface finish, and extend tool life, offering a superior, cost-effective solution for your production needs.

Key Features & Benefits

  • Exceptional Taper Accuracy:Manufactured to an exacting taper tolerance of ±2μm and verified with German Diebold inspection equipment. This guarantees a perfect fit with the machine spindle, maximizing rigidity, ensuring consistent power transmission, and reducing spindle wear.

  • Superior Hardness & Durability:Crafted from a proprietary, self-developed H13 alloy steel and uniformly heat-treated to a Rockwell hardness of HRC 50-53. This results in exceptional wear resistance, high-temperature stability, and a long operational lifespan, even under heavy-duty machining conditions.

  • High-Speed Dynamic Balance:Meticulously balanced to a G2.5 grade at 25,000 RPM. This ultra-fine balancing minimizes vibration, protects spindle bearings, and is critical for achieving superior surface finishes in high-speed machining (HSM) operations.

  • Ultra-Low Runout for Ultimate Precision:With a guaranteed runout accuracy controlled to within 3μm (0.003mm), our tool holders provide outstanding concentricity. This directly translates to superior workpiece accuracy, predictable cutting performance, and significantly extended cutting tool life.

  • Optimized for Performance & Value:Our newly upgraded design and streamlined manufacturing processes allow us to offer these high-performance machine tool accessories at a competitive price point. This provides an excellent return on investment for wholesale distributors and large-scale manufacturing operations seeking quality and affordability.
