1pc CNC Carbide Flat End Mill Tungsten Cutter 2 4 Flute Metal Steel Machining Tool Key Face Square Router Bit 6 8 12 Shank HRC55 (Color : 4F-BK2045, Size : 4x4x18x75)

Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid tool-holding systems.DementionsTolerance of End Mill Diameter:<; D6 -0.010 ~ -0.030<; D10 -0.015 ~ -0.040<; D 20 -0.020~-0.050Industrial DesignNegative front angle and large chip space.Easier roughing and finishing processing. Decreasing the times of changing cutters,Saving production time.Helix Angle:35 deg, high adaptability to the material and hardness of workpieces, widely used to mold and product processing and cost efficient.Coating:Good coating can improve tools life and production efficiency, as well as solve the cutting problems.ApplicationUsed in Milling Machine.,CNC,Drill press,Engraving machine. Metal, woodworking, alloy steel, stainless steel, etcBB 2 flutes end mills is widely used in slotting, sinking etc.3 flutes for aluminum,non-ferrous metal.4 flutes, high rigidity, widely used in shallow slot, profile milling, and finish machining.Carbide End MillsColor: Dark grey.Density: 14.5 g/cm3Hardness: HRA 91.5Grain Size: 0.8umBending Strength: 2800N/mm2Raw material: Recycled material,YG10X with 10% Co content and 0.8um grain size. Because tungsten is a scarce resource, BK2045 series milling cutter is made of recycled tungsten steel.Coating: ALTiN,High aluminum content provides excellent hot hardness and oxidation resistance.A good choice for milling general steels weaker than HRC 30. But, because of the aluminum content, it is not good choice for aluminum.
