Two new grades to tackle the extreme demands of titanium milling are now being launched by Sandvik Coromant . Grades S30T and S40T are available for a variety of CoroMill cutters for:
- High feed milling
- Slot milling
The S30T grade has been developed with productive titanium milling in focus. It combines the properties of micro-grain carbide and a wear resistant PVD coating. This enables very sharp cutting edges that resist fatigue and micro-chipping and result in cutting edges that are preserved for longer times in cut at higher cutting speeds.The S40T grade is developed for difficult conditions. It 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.
