High-Performance Solid Carbide Drill Tips
The WS... RT19 interchangeable drill tips cover the diameter range from 12,50 to 12,90 mm and are a well-thought-out solution for professional drilling operations in steel and cast iron. The CVD-coated P25/K20 carbide grade provides convincing wear resistance that supports efficient workflows in machining. Please pay attention to the carrier/drill bit combinations! These drill bits only fit the 12,50-12,90 mm carrier. When using the 5xD or 8xD drill body, we recommend reducing the feed rate to 85% or 70%.

Applications
Thanks to the specific P25/K20 cutting material design, this drilling system is excellently suited for the universal machining of non-alloy steel, low alloy steel, and high alloy tool steel. Furthermore, the drill tip performs reliably in grey cast iron, nodular cast iron, and malleable cast iron. The interchangeable system creates good conditions for flexible adaptations in modern mechanical engineering and fixture construction.
Special features
The 140° point angle enables precise centering and ensures an even distribution of cutting forces. The wear-resistant RT19 CVD coating is specifically tailored to the requirements of machining steel and cast materials. In combination with the matching WST holders in various lengths (3xD, 5xD, 8xD), it results in a highly stable tool system tailored for professional use.
