CERMET
- NX2525 for high speed milling.
- NX4545 for general milling.
Micro-Structure of NX2525
Micro-Structure of NX4545
- NX2525 has high hardened Ti compound particles within it's microstructure therefore the grade has both excellent wear and fracture resistance properties.
- NX4545 uses a special alloy for the binder material therefore the grade has high fracture resistance properties.
SELECTION STANDARD
MILLING
(Note) In case of wet cutting, please use coated carbide F7030 for steel cutting and coated carbide F5010 for cast iron cutting.
