FAQ

Q1: What is the difference between BT Hydraulic Tool Holders and BT Rear Pull Tool Holders?
A1: BT Hydraulic Tool Holders use a hydraulic clamping system for uniform, high clamping force, while BT Rear Pull Tool Holders mechanically pull the tool from the back for secure retention. Both provide precision, but hydraulic holders offer superior stability under high-speed or heavy-load operations.


Q2: Which shank sizes are available?
A2: Our product line includes BT30 Hydraulic Tool Holders and BT40 Hydraulic Tool Holder options compatible with standard CNC machines.


Q3: Are these holders suitable for high-speed CNC turning?
A3: Yes, our BT CNC Tool Holder and Hydraulic Chucks are designed for high-speed CNC turning and milling, maintaining minimal runout and stability at high RPM.


Q4: Can custom sizes be made?
A4: Yes, we provide customization for shank size, holder length, and specific hydraulic clamping requirements to meet client needs.


Q5: What industries use these tool holders?
A5: Widely used in CNC machining centers, mold manufacturing, aerospace, automotive, and industrial metalworking.


Our BT Hydraulic Tool Holders range—including BT30 Hydraulic Tool Holders, BT40 Hydraulic Tool Holder, BT40 Hydraulic Chuck, BT Rear Pull Tool Holder, BT Tool Holder, Rear Pull Tool Holder, BT Shank Tool Holder, Precision BT Tool Holder, and BT CNC Tool Holder—offers unmatched precision, durability, and versatility. Designed for high-speed CNC milling, turning, mold manufacturing, aerospace, and industrial applications, our tool holders ensure reliable tool clamping, minimal runout, and superior machining accuracy.
