Key Features & Technical Highlights:
1.Excellent Concentricity: High-precision versions can achieve a tool tip runout (T.I.R.) of ≤ 3 µm measured from the internal taper to the external taper. This ensures exceptional accuracy and fine surface finishes.
2.Optimized for High Speeds: These toolholders are fully balanced, typically to a quality grade of G2.5 at 25,000 rpm or higher, minimizing vibration during high-speed machining.
3.Enhanced Rigidity & Pull-Out Resistance: The BT flange interface (7:24 taper) provides a stable connection. Some high-performance variants, like the BBT (Big-BT) series, feature a "two-side clamp" or dual-contact design, engaging both the taper and the face of the spindle nose for maximum rigidity and precision under high centrifugal forces.
4.Superior Surface Finish & Damping: The refined design and precise manufacturing contribute to improved damping characteristics, which can help achieve superior surface quality on the workpiece.
