In the evolving landscape of precision manufacturing, BMT Live Driven and Static Tool Holders play a pivotal role in enabling high-performance turning, drilling, and milling operations on modern CNC lathes. These holders provide a robust interface between the machine turret and cutting tools, allowing manufacturers to achieve exceptional accuracy, repeatability, and productivity. Whether deployed in high-speed machining centers or multi-tasking turning centers, BMT tool holders—both live driven and static—enhance machining flexibility and reduce setup times, making them essential components for industries demanding precision and efficiency. By integrating these holders into CNC operations, manufacturers can optimize tool performance, improve surface finish, and maintain dimensional accuracy even on complex geometries.
BMT Live Driven Tool Holders are designed to transmit spindle power directly to rotating tools such as drills, end mills, or taps. This functionality enables simultaneous turning and milling operations, allowing operators to perform drilling, tapping, and milling on the rotating workpiece without manual repositioning. Live driven holders are particularly effective for multi-tasking lathes, where reducing cycle time and setup complexity is critical. In contrast, BMT Static Tool Holders serve as rigid mounts for stationary tools such as turning inserts, boring bars, and grooving tools. They provide high rigidity and stability for conventional turning, facing, and threading operations. Together, live driven and static BMT holders offer a complete solution for modern CNC lathes, allowing manufacturers to tackle complex components such as automotive transmission housings, aerospace brackets, and precision medical parts with minimal downtime and maximum efficiency.
Live Driven Holders: High-precision bearings, torque transmission efficiency, programmable rotation speed, and internal coolant channels to maintain tool life and optimize chip evacuation.
Static Holders: Rigid clamping, anti-rotation mechanisms, vibration damping design, and easy insert change systems.
Both types feature modular design compatibility with BMT turret interfaces, allowing for quick tool swaps and flexible machining setups. Additionally, precision-ground alignment surfaces and minimal runout ensure superior dimensional accuracy and surface finish, even under high-speed or heavy-duty cutting conditions. Many models also provide coolant-through capability, enabling direct cooling at the cutting edge for increased productivity and reduced thermal deformation.
Mounting Standard: BMT turret interface
Tool Compatibility: Live driven holders support drills, end mills, taps, and small milling cutters; static holders support turning inserts, grooving bars, and boring tools
Rotational Speed (Live Driven): Up to 12,000 RPM depending on model
Torque Ratings (Live Driven): 10–200 Nm
Runout Precision: ≤ 0.005 mm to ensure high accuracy and surface finish
Coolant Supply: Optional through-tool coolant for live driven holders

These specifications provide users with the assurance of compatibility with a wide range of CNC machines, high-speed operations, and complex multi-axis machining processes.
For optimal performance and longevity, correct setup and handling of BMT Live Driven and Static Tool Holders are essential. Operators should securely mount the holder to the turret, verify alignment, and ensure proper clamping torque according to manufacturer guidelines. Live driven holders require inspection of the spindle and drive components, lubrication of bearings, and verification of rotation smoothness before operation. Coolant flow should be checked to prevent overheating and optimize chip evacuation. Static holders demand attention to insert positioning, torque settings, and anti-rotation alignment to maintain dimensional accuracy. Regular inspection and maintenance, including cleaning, lubrication, and checking for wear or runout, will extend tool life and maintain consistent machining quality.
