1Mm X 10Mm X 4Mm X 50Mm Altisin Coated Carbide 4 Flute Square End Mill 2Pcs

Made of super fine grain carbide, the end mill cutter has high hardness (HRC92), high strength, and wear resistance. With good milling and cutting performance, carbide can run at higher speed than high-speed steel. Features square end cut, 4-flute design, large and spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting. The AlTiSin composite coating has high hardness, high wear resistance and high thermal stability. Suitable for cutting stainless steel, carbon steel, malleable cast iron, alloy steel, die steel, tool steel etc.. The clearance part is the same as the cutting diameter, specially designed for machining deep holes and deep grooves. Used for groove machining, side milling and finishing. Use on CNC machining centers, CNC machine tools, precision engraving machines and other equipment. Universal chamfered round shank for easier clamping and stable cutting process.The longer the length of the tool clamped by the chuck, the better. Notice: If the clamping length is shorter, you need to lower the feed rate and cutting speed to reduce vibration and extend the tool life. Combined with the material to be processed, select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.
