    VER Split Synch Tapping Chuck - Durable & Affordable Solutions from China Suppliers & Factory for Precision Tapping

    Introducing our high-quality VER tapping chuck, designed to enhance efficiency and longevity in machining operations. This China-manufactured chuck minimizes errors between spindle rotation and tool feeding, significantly extending the lifespan of your tapping equipment.
    Our unique split-type structure allows for easy replacement of the front worn-out part, making it a cost-effective solution while preserving the main components of the chuck.
    The VER tapping chuck can handle coolant flow pressures of up to 2MPa, ensuring optimal performance even in high-demand applications.
    Additionally, the side fixing screw in the VER extender addresses common torque support issues encountered with ER sealing collets and taps, providing a reliable connection for your tools.
    This versatile chuck accommodates longer-size tapping collets for various tapping depths, with capacities ranging from M3 to M12, M6 to M20, and M14 to M33.
    Compatible with spindle standards including HSK (DIN69893), BT (JIS B6339), and SK (DIN69871), our tapping chuck is an essential tool for any supplier or factory looking to optimize their machining processes.

      DEREK Necessity Reminder For VER Lock Holder

      VER Lock Holder Installation
      Due to split connection mechanism of VER , the VER extender must be installed in the VER lock holder before the nut is operated (figure A);
      If the nut is operated in the VER overall connection state, the connection mechanism will be damaged (Fig. B).

      DEREK Frequently Asked Questions (FAQ)

      What is the primary advantage of the DEREK VER Split Synchronous Tapping Chuck?
      The VER chuck prevents synchronization errors between spindle rotation and tool feed, significantly prolonging tool life by 80% or more and boosting working efficiency by 2 to 4 times compared to standard tapping chucks.
      How does the split-type structure save machining costs?
      The unique split-type design allows operators to replace only the front worn-out component instead of replacing the entire body, retaining the main part of the chuck and substantially cutting maintenance costs.
      Why is the VER Lock Holder required during installation?
      Due to the split connection mechanism, the VER extender must always be placed into the dedicated VER lock holder before tightening or operating the nut. Tightening the nut while in the overall connection state can severely damage the internal mechanism.
      What spindle shank standards are supported by the VER series?
      The system supports all common international standards, including HSK (DIN69893), BT (JIS B6339), SK (DIN69871), DCK, and straight-shank C-VER configurations.
      What coolant pressure can the VER tapping chuck withstand?
      The chuck supports through-spindle coolant flowing pressures up to 2.0 MPa, providing optimal chip evacuation and cooling for demanding squeeze tapping operations.
      Are collets, extenders, and wrenches included in the basic chuck package?
      No, extenders, ER tapping collets, and dedicated wrenches (such as WGSK and TSK series) must be ordered separately according to your specific tapping size and machine requirements.
