A BT Series Tool Holder is a CNC tool holding device used to securely connect cutting tools with machine tool spindles. It is widely applied in CNC machining centers, milling machines, and automatic tool changing systems due to its excellent rigidity, precision, and stability.
The BT tool holder adopts a 7/24 taper design, which provides accurate positioning and strong clamping force between the tool holder and spindle. It is one of the most commonly used tooling standards in global CNC machining industries.
Available sizes include BT30, BT40, and BT50 Tool Holders, allowing manufacturers to select suitable solutions for different machining requirements, from precision processing to heavy-duty cutting applications.
The main purpose of a BT Series Tool Holder is to provide a stable connection between the CNC spindle and cutting tools.
The 7/24 taper structure ensures:
Accurate tool positioning
Strong gripping force
Reduced vibration
Stable cutting performance
When the CNC machine operates, the spindle pulls the BT tool holder into the spindle taper, creating a rigid connection that improves machining accuracy.
BT Tool Holders are commonly used with CNC machines equipped with automatic tool changers (ATC).
The automatic tool changing process allows:
Fast tool replacement
Reduced machine downtime
Improved production efficiency
Continuous machining operations
This makes the BT Tool Holder an ideal choice for high-volume manufacturing.
The BT40 Tool Holder is the most widely used size in CNC machining applications.
It provides a balance between rigidity and flexibility, making it suitable for:
CNC milling machines
Mold machining
Precision component manufacturing
General industrial machining
BT40 tool holders are commonly selected for medium-load machining operations.
The BT50 Tool Holder is designed for heavy-duty machining applications requiring stronger cutting capability.
