Product Advantages
BBT Dual Contact
The BBT taper contacts both the spindle taper and flange simultaneously, significantly improving rigidity and reducing vibration during high-speed machining.
01
High Clamping Force
Shrink-fit technology provides uniform 360° tool clamping without hydraulic components or collets, ensuring excellent machining stability.
02
Face Coolant Design
Coolant is delivered directly to the cutting zone through the front outlet, improving heat dissipation, reducing built-up edge, and increasing machining efficiency.
03
High Precision
Precision grinding and strict quality control guarantee ultra-low runout, helping improve dimensional accuracy and surface finish.
04
High-Speed Machining
Each holder is dynamically balanced to minimize spindle vibration and maintain stable performance at high rotational speeds
05
