CERMET

NX1010 for high speed turning. NX2525 for general turning and high speed milling. NX4545 for general milling.

		NX2525 has high hardened Ti compound particles within it's microstructure therefore the grade has both exellent wear and fracture resistance properties. NX4545 uses a special alloy for the binder material therefore the grade has high fracture resistance properties.

SELECTION STANDARD

TURNING (Note.)In case of wet cutting, please use coated cermet grades as fracturing is more difficult to occur . MILLING (Note.)In case of wet cutting, please use coated carbide F7030 for steel milling and coated carbide F5010 for cast iron milling.
