Insert grades that do not chemically react with titanium.

With the new Perfomax, Seco has made an excellent drill even better.

The new DS2050 and DS4050 insert grades have niobium nitride (NbN) top layers that do not chemically react with titanium. The prevention of that reaction — the most common wear factor with titanium — significantly extends tool life.

The combination of both heat and wear resistance with the DS2050 and DS4050 coatings makes these inserts a first choice for drilling titanium and high-temp superalloys as well as difficult stainless steel materials. The grades enhance productivity and extend tool life thanks to newly developed free-cutting MP and MC chip breakers.
