These cutters are coated with Zirconium Nitride (Zrn). This is a specialty coating which makes it most suitable for temperature sensative materials. ZrN had excellent corrosion-resistance, lubricity and hardness to suit many applications. This coating has a unique ability to reduce the build-up edge on cutting tools which results in a better surface finish.

ZrN works well for machining Titanium and Aluminum Alloys, Nickel, Brass, Copper, Cast Iron and Zinc.
