The gray PVD coating greatly enhances the ability of the blade to resist abrasive wear and adhesive wear (transfer of chips and tool surface materials), significantly extending tool life, and is suitable for medium and low-speed precision machining and semi precision machining of various stainless steels.

When excellent edge strength and high surface quality are required, providing perfect smooth cutting reduces the friction between chips and the front cutting surface of the tool, as well as between the workpiece and the back cutting surface of the tool during the cutting process, thereby reducing cutting force, cutting temperature, and power consumption, and improving the surface effect of the machined surface.
Long processing life, high cost-effectiveness, good working range, high thermal shock resistance, suitable for intermittent cutting. Strong toughness and impact resistance.
