End mills can be used for CNC machine tools and ordinary machine tools. It can  most common processing, such as slot milling, plunge milling, contour milling, ramp milling and profile milling, and is suitable for a variety of materials, including medium-strength steel, stainless steel, titanium alloy and heat-resistant alloy. Coating: AlTiSiN, with the hardness and thermal stability are up to 4000HV and 1200℃, respectively Tolerance of End Mill Diameter:1 ＜ D≤6 -0.010 ～ -0.030;6 ＜ D≤10 -0.015 ～ -0.040;10 ＜ D≤20 -0.020 ～ -0.050

1.Use nano-tech, the hardness and thermal stability are up to 4000HV and 1200 degree, respectively. 2. Double-edge design improves rigidity and surface finish effectively. Cutting edge over the center reduces the cutting resistance. High capacity of junk slot benefits chip removal and increases machining efficiency. 2 flutes design is good for chip removal, easy for vertical feed processing, widely used in slot and hole processing. 3. 4 Flutes, high rigidity, widely used in shallow slot, profile milling and finish machining. 4. 35 deg, high adaptability to the material and hardness of workpiece, widely used to mold and product processing and cost efficient.
