YG1 55903TE 1/2″ Size, 1-1/2″ LOC, 4 Flute, YG TiAlN Extreme Solid Carbide Finishing End Mill Super Sale

Applications

With a 3.0x length-to-diameter ratio, the YG1 55903TE 1/2″ diameter, 1-1/2″ length of cut solid carbide end mill provides a balance of rigidity and reach suitable for medium-depth slotting and pocket milling. Featuring a four-flute design, a 30° helix angle, and YG TiAlN Extreme coating, it improves chip evacuation and wear resistance, enabling efficient milling in steel and cast iron. This configuration is particularly effective for free-machining steel, aligning with recommended general milling parameters. The absence of a corner radius focuses the tool on precision finishing rather than interrupted cuts, minimizing chipping risk in continuous operations. The TiAlN Extreme coating offers thermal stability and hardness, extending tool life under moderate to high cutting speeds. Avoid this end mill on non-ferrous materials due to coating unsuitability, which may cause rapid wear. Its geometry and coating do not suit plastics or soft metals, where alternative flute counts and coatings perform better.

Features

• Suitable for cutting hardened & high alloy steels, steel casting, chill casting, malleable cast iron, CrNi-steels, brass, copper, aluminum with a high percentage of silicon and abrasive plastics.
