High-Performance Drill Tip for Steel and Cast Iron

With the WS... RT19 solid carbide drill tip in the 33.00 to 33.73 mm range, you receive a tool designed for demanding drilling tasks. The design utilizes the CVD-coated RT19 grade (P25/K20), which creates good conditions for machining non-alloy, low alloy, and high alloy steels as well as various cast iron types. Combined with the matching WST D33.0-..xD-H holder, it supports efficient workflows.

Applications

This tool is focused on universal drilling in steel and cast iron materials. It is widely used in mechanical engineering, manufacturing technology, and general tool and mold making. The drill tip is built to create solid holes across a broad spectrum of ISO material groups (P and K), making it a practical choice for everyday production.

Special features

Please pay close attention to the holder and drill bit combination. These tips only fit the WST D33.0-..xD-H holder. When using the 5xD or 8xD drill body, we recommend reducing the feed rate to 85% or 70% respectively, to support a stable and reliable machining process. The ability to quickly exchange the insert within the holder system helps reduce setup times in professional environments.
