High-Performance Carbide Inserts for Metal Machining

The inserts of the WS... RT19 series in the diameter range of 29.00 to 29.77 mm offer a well-thought-out solution for demanding drilling tasks. They feature a high-quality CVD coating and are geared towards professional use in steel and cast iron materials. Please pay attention to the holder/drill bit combinations! These drill bits only fit the WST D29.0-..xD-H holder (29.00 to 29.77 mm). When using the 5xD or 8xD drill body, we recommend reducing the feed rate to 85% or 70%.

Applications

These interchangeable tips are designed for industrial applications in non-alloy, low-alloy, and high-alloy steels, as well as grey, nodular, and malleable cast iron. With their precise alignment to the WST holder system, they open up flexible application possibilities in modern machining and support efficient drilling workflows.

Special features

The robust solid carbide insert convinces with its universal RT19 CVD coating, which provides good wear resistance. The 140° point angle creates favorable conditions for stable drill machining and precise centering across various steel and cast iron materials.
