High-Performance Solid Carbide Drill Tips for Machining

The WS RT19 solid carbide interchangeable drill tips (diameter 22.00 to 22.90 mm) are designed to efficiently handle demanding drilling operations in industrial applications. Thanks to the practical interchangeable head system, they support quick tool changes directly on the machine, thereby reducing valuable setup time. The drill tips are precisely matched to the corresponding tool holders and offer excellent repeatability.

Please pay attention to the holder/drill bit combinations!
These drill bits only fit the WST D22.0-..xD-H holder (22.00 to 22.90 mm).

Applications

These solid carbide drill tips are specifically designed for the universal drilling of unalloyed, low-alloyed, and high-alloyed steel, as well as grey, nodular, and malleable cast iron. They prove particularly effective in medium to large production runs in mechanical engineering, where consistent performance and reliable hole quality are required.

Special features

The RT19 grade combines a tough P25/K20 carbide substrate with a highly wear-resistant CVD coating. This combination creates excellent conditions for long tool life and secure machining processes. The 140° point angle promotes precise centering and ensures an even distribution of cutting forces when processing robust materials.
