-
Cutting Applications: Designed for milling, specifically for high-feed (HRM Double) milling systems with up to 6 usable cutting edges.
Why It’s a Best Seller
-
Outstanding wear resistance and oxidation stability, thanks to its advanced PVD coating.
-
High toughness resists chipping and fracture even under interrupted cuts or in long-overhang/deep shoulder milling.
-
Reduced built-up edge and strong adhesion mean longer tool life → fewer tool changes → lower cost per component.
6-edge double-sided design for efficient tool usage and lower per-edge cost.

Frequently Asked Questions
The PC5400 grade is a universal grade covering ISO P (steel), M (stainless), K (cast iron), and S (heat-resistant alloys), making it highly versatile
While both are universal grades, PC5400 is optimized for medium-to-low speed and interrupted cutting, thanks to its tougher substrate and lubricative PVD coating.
The WNMX09T316ZNN geometry is double-sided, offering 6 usable cutting edges, which helps reduce the cost per corner.
Yes — this insert was specifically designed for those challenging conditions, including deep shoulder cuts and ramping, with high edge rigidity and chip control
The AlCiN-based PVD coating provides excellent lubrication and strong adhesion, reducing welding, chipping, and fracture risks even in wet, interrupted cuts.
