High-performance solid carbide drill tips for the WST system
The interchangeable drill tips WS... RT19 in the 21.00 to 21.90 mm range provide a robust design for professional drilling applications. The CVD-coated P25/K20 carbide grade creates favorable conditions for the reliable machining of non-alloy, low-alloy, and high-alloy steel, as well as various cast iron materials.
Please pay attention to the holder/drill bit combinations!
These drill bits only fit the WST D21.0-..xD-H holder (21.00 to 21.90 mm).

Applications
Thanks to the versatile RT19 grade, this interchangeable tip is well-suited for machining a wide variety of steel and cast iron materials. It supports efficient workflows in the metalworking industry, particularly when frequent changeovers between different ISO P and ISO K materials are required.
Special features
The 140° point angle offers a well-balanced combination of stability and precise cutting performance. The sophisticated interchangeable tip concept allows for quick tool changes directly in the machine, which can reduce downtime and increase the economic efficiency of drilling operations.
