High-Performance Drill Tip WS RT19
The interchangeable WS RT19 drill tip provides professionals with a resilient and efficient solution for drilling applications in the 28.00 to 28.97 mm diameter range. The combination of a P25/K20 carbide substrate and a wear-resistant CVD coating creates excellent conditions for machining unalloyed and alloyed steel, as well as grey and nodular cast iron. By using the WST D28.0-..xD-H holder, the cutting edges can be replaced directly in the machine, accelerating workflows and improving machine availability.
Please pay attention to the holder/drill bit combinations!
These drill bits only fit the WST D28.0-..xD-H holder (28,00 to 28,97 mm).
