China HSK Angle Head Series - High Precision Tool Holder from Reliable Suppliers & Factory

Introducing our advanced cutting tool designed for optimal performance in machining applications. This cutting tool rotates in reverse to the machine spindle, enhancing precision and efficiency. Included with your purchase are a wrench and nut, while the collet must be ordered separately to ensure compatibility. One of the standout features is the adjustable angles of the Locating Pin in relation to the drive key groove and cutting edge direction, allowing for customized setups tailored to your specific needs, Please note that a Stop Block is essential for mounting this tool onto machines; this component needs to be ordered separately. The design facilitates the cooling liquid to reach the cutting edge directly from the tool body when using the Stop Block, ensuring effective temperature management during operation, It’s important to keep in mind that while our tool supports various machines, auto tool change functions may not be available for all models. Additionally, this tool is designed with a non-central coolant feature, As a leading manufacturer and supplier from China, our factory is committed to providing high-quality cutting tools that meet the demands of modern machining processes. Elevate your productivity with our expertly crafted tools today!

    Frequently Asked Questions
    Q What is the drive ratio of the HSK Angle Head DG90 Series?
    A The majority of HSK Angle Head DG90 Series models feature a 1:1 drive ratio, meaning the angle head spindle rotates at the same speed as the machine spindle. Some special variants, such as the tapping heads (TC12/TC20), use a 2:1 deceleration ratio, while certain collet adapter models offer 1:1.06 acceleration or 1:0.77 deceleration ratios depending on the application.
    Q Is a Stop Block required for mounting HSK Angle Heads on machines?
    A Yes, a Stop Block is required when mounting any HSK Angle Head on a machine. The Stop Block must be ordered separately. It also serves as the coolant inlet — cooling liquid can reach the cutting edge through the tool body when routed via the Stop Block.
    Q Are collets included with the HSK Angle Head DG90 Series?
    A Collets are not included and must be ordered separately. However, wrench and nut are typically included with standard ER collet models. For lightweight and out-internal cooling series, an oil sealed clamp nut and adjusting screw are included, but the collet itself still needs to be ordered separately.
    Q What is the difference between the Standard and Powerful versions of the HSK Angle Head?
    A The "Powerful" version is designed for higher torque and more demanding cutting applications, and it generally weighs slightly more than the Standard version. Both versions share the same dimensional specifications (length, clamping diameter, etc.), so they are interchangeable in terms of mounting. The Powerful version is recommended for heavy-duty milling and drilling operations.
    Q Can the cutting angle direction be adjusted on these HSK Angle Heads?
    A Yes. The angle of the Locating Pin relative to the drive key groove, as well as the direction of the cutting edge, are freely adjustable on all models in the HSK Angle Head DG90, DG45, and DGU series. This provides flexible setup for various machining orientations without requiring additional tooling.
    Q Is automatic tool change (ATC) supported for HSK Angle Heads?
    A Automatic tool change (ATC) compatibility depends on the specific machine model and configuration. It may be unavailable on some machines. Please verify ATC compatibility with your machine tool supplier or contact us before ordering if ATC functionality is a critical requirement for your application.
