BBT Angle Head DG90 Series - High Precision Tooling from China Suppliers and Factory

Introducing our high-quality cutting tool designed for precision machining. This innovative tool features a reverse rotation mechanism that enhances performance and adaptability in various manufacturing settings. Included with your purchase are a wrench and nut, while collets should be ordered separately for maximum versatility, One of the standout features of our cutting tool is the adjustable angles of the Locating Pin, allowing you to align the drive key groove and cutting edge direction to suit your specific needs. For optimal mounting on machines, a Stop Block is required, which is available for separate order. This setup also ensures that cooling liquid can efficiently reach the cutting edge through the tool body, enhancing tool longevity and performance, Be aware that auto tool change functionality may not be supported on all machines, so it's essential to verify compatibility. Sourced from reliable suppliers in China, our factory produces cutting tools that meet rigorous standards for quality and efficiency. Elevate your machining capabilities with our advanced cutting tool solution!

Important Notes

■ When ordering, provide us with the manufacturer, model and specifications of the machine tool, as well as the BIG product model number.

■ Kindly inquire us regarding Stop Block and mounting dimensions.

■ Kindly check with the machine tool manufacturer for the shape of the Stop Block, as it will vary for each machine tool model.

■ The dimension from the spindle gauge line to the top of the Stop Block (※) is our standard length.

▲ As the Air Turbine requires clean air, do not share the same Stop Block with other products.

Frequently Asked Questions

Q What is a BBT Angle Head and what is it used for?

A BBT Angle Head is a precision tooling attachment used on CNC machining centers. It redirects the cutting tool axis at 90° (or 45°) relative to the machine spindle, enabling machining of side faces, cross holes, and complex contours without repositioning the workpiece. BBT30, BBT40, and BBT50 refer to the taper shank size compatible with the machine spindle.

Q Is a Stop Block required when using BBT Angle Heads?

Yes. A Stop Block is required when mounting BBT Angle Heads on machines. It prevents the angle head body from rotating during machining. Stop Block dimensions vary by machine model, so please consult your machine tool manufacturer or contact us with your machine specifications for the correct Stop Block.

Q Do the collets come included with the angle head?

In most models, the wrench and nut are included, but the collet must be ordered separately. Please specify the required collet type (e.g., ER11, ER16, ER20, ER32) when placing your order. For tapping models and certain special types, collets are also not included.

Q Can coolant be supplied through the BBT Angle Head to the cutting edge?

Yes, in most DG90 series models, cooling liquid can reach the cutting edge through the tool body when routed via the Stop Block. For the Oil Hole Type (ODG90), coolant must always be supplied — never run the unit without coolant. For Face Milling type, cooling liquid cannot pass through the positioning bolt.

Q Is automatic tool change (ATC) supported with BBT Angle Heads?

Automatic tool change may not be available depending on the machine tool model. Please verify compatibility with your machine tool manufacturer before use. Some machine configurations may require manual tool changes when using angle heads.

Q What is the difference between the Standard and Powerful versions of BBT Angle Heads?

The "Powerful" version typically features a reinforced internal structure designed for higher torque and more demanding cutting applications, and is slightly heavier than the Standard version. Both versions share the same 1:1 drive ratio and external dimensions; the choice depends on your machining load requirements. Powerful versions are available in Distance 80 and Distance 110 configurations for BBT50.
