Double-Sided Contact Design
The BBT-ER tool holder adopts a design where both the 7:24 taper face and the end face make contact simultaneously, ensuring a more stable connection between the tool holder and the spindle. This design not only improves rigidity but also significantly reduces vibration during machining, thereby enhancing surface finish quality and tool life.

High Precision and Rigidity
The manufacturing precision of the tool holder reaches ≤0.003mm, ensuring stability and consistency during high-speed machining. The preset dynamic balance design (G2.5, 25000 RPM) further reduces vibration during high-speed rotation, making it suitable for high-precision machining requirements.

Superior Material and Hardness
Made from 20CrMnTi material and heat-treated to a hardness of HRC56°, the tool holder exhibits excellent wear resistance and anti-deformation capabilities under high-load machining conditions.

Wide Range of Applications
The BBT-ER tool holder is suitable for various CNC machine tools, particularly excelling in high-precision and low-vibration machining scenarios. Whether for milling, turning, or drilling, the BBT-ER tool holder delivers stable performance.
