HARFINGTON Square End Mill 3mm x 8mm Cutting 6mm Shank Micro Grain Solid Carbide AlTiN Coated 2 Flutes Milling Bit Cutter for Alloy Hardened Steel Aluminum

Micro Grain Solid Carbide end mill cutter offers high hardness, wear resistance, and heat resistance. Carbide material with good milling and cutting performance, run at higher speed than high-speed steel.Square end cut, 2-flute design, spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting. Premium AlTiN (high aluminum & titanium)composite coating can increase hardness and wear resistance, and apply lubricant better for smoother milling and longer service life.The milling bit is suitable for cutting alloy steel, stainless steel, carbon steel, cast iron, tool steel, hardened steel, great for shallow groove machining, side milling and finishing. Works with CNC machining centers, engraving machines and other high-speed CNC machine tools.The longer the length of the tool clamped by the chuck, the better. If the clamping length is shorter, you need to lower the feed rate and cutting speed to reduce vibration and extend the tool life.Notice: 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.
