High-Performance Solid Carbide Drill Tip WS RT19
The CVD-coated solid carbide drill insert WS RT19, available in diameters from 19.00 to 19.90 mm, is an excellent choice for the professional machining of steel and cast iron. Combining a 140° point angle with the proven P25/K20 carbide grade, this insert creates ideal conditions for reliable, universal drilling operations. Please pay attention to the carrier/drill bit combinations! These drill bits only fit the 19.00-19.90 mm carrier. When using the 5xD or 8xD drill body, we recommend reducing the feed rate to 85% or 70%.

Applications
The RT19 drill tip is engineered for universal drilling in non-alloy, low-alloy, and high-alloy steel as well as grey, nodular, and malleable cast iron. It supports efficient workflows in mass production and general mechanical engineering, where process stability and consistent bore quality are essential.
Special features
Thanks to the durable CVD coating and the robust P25/K20 matrix, users benefit from convincing wear resistance that holds up well even under demanding machining conditions in steel and cast iron. The 140° point angle facilitates secure spot drilling and contributes significantly to stable cutting behavior. The intelligent interchangeable system ensures quick and easy tool changes within the corresponding WST drill carrier.
