Grades S30T and S40T from Sandvik Coromant enable users to tackle the extreme demands of titanium milling. The materials are used for a variety of CoroMill cutters for face, shoulder, long-edge, and high-feed milling, plunging, profiling, and slot milling. S30T combines the properties of micrograin carbide and a wear-resistant PVD coating. This enables sharp cutting edges that resist fatigue and microchipping, thus preserving the edges for longer times in cut at higher cutting speeds. S40T is developed for difficult conditions and combines high-toughness cemented carbide with a thin CVD coating. The result is a grade that withstands vibrations and other difficult cutting conditions for longer times in cut. The wear is predictable, making the cutting edge gradually duller without breaking.
