This is a two pack of Zrn coated flat mills from Carbide 3D that are perfect for fabricating with aluminum. Each mill in this pack features a cutting and shank diameter of 0.25 inches and a cutting length of 0.75 inches. These cutters really are great for precision 3D machining and fabrication.
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. Each cutter is made of solid carbide to ensure long lasting use.
