High-performance drill base for modular systems

The WST interchangeable tip drill serves as an essential tool holder for professional bore machining. Designed to accommodate drill inserts in the diameter range of 21.00 to 21.90 mm, it provides users with high flexibility for various drilling tasks. Available in usable lengths of 3xD, 5xD, and 8xD, this base enables efficient operations for both shallow and deeper holes. The modular design ensures short setup times, as only the tip needs to be changed while the robust holder remains securely in the machine.

Important note: Please pay attention to the Holder/drill bit combinations! Only drill bits with a diameter of 21.00-21.90 mm fit on these supports.

Applications

This drill base is designed for professional use in the metalworking industry, mechanical engineering, and series production. When equipped with appropriate carbide drill inserts, the system is perfectly suited for producing precise bores efficiently. The different length options support a wide spectrum of component geometries and manufacturing requirements.

Special features

A key feature of this system is the ability to change cutting tips directly on the machine quickly, which minimizes valuable non-productive times. The reliable seat guarantees firm clamping of the inserts, promoting smooth operations with reduced vibrations. This establishes the foundation for high tool life and repeatable machining accuracy.
