Machinists and CNC operators, this uxcell end mill cutter is built for serious cutting performance! With a 5/8 inch cutting diameter and matching 5/8 inch shank, this 4-flute spiral end mill is made from HSS-AL (high-speed steel with aluminum treatment) that gives you excellent bending resistance and wear resistance. The cutting length is 1-5/8 inches with an overall length of 95mm (about 3.74 inches), making it versatile for various milling operations. The deep helical grooves are designed for efficient chip removal, which really helps improve your machining efficiency and gives you cleaner cuts. This end mill works great on carbon steel, soft alloy steel, die steel, tool steel, cast iron, titanium, aluminum, and other materials - it's seriously versatile for different workshop projects. It's perfect for CNC data processing centers, carving machines, and high-speed machining applications. Just make sure your workpiece and machine are stable, and use proper chucks like hydraulic chucks, collet chucks, or shrink fit chucks for the best results. You'll want to adjust the speed, feed rate, and cutting depth based on your specific material and conditions. The cutter comes in a protective plastic box to keep it safe between uses. Seriously, if you need a reliable end mill that can handle high-speed cutting applications without breaking down, this uxcell cutter delivers professional-grade performance at a very reasonable price point for both hobbyists and professional machinists!
