3 Flute Carbide End Mill-HRC 65°-50 to 200mm Long CNC Tool For Alu, zinc, copper

3 Flute Carbide End Mill-HRC 65°-50 to 200mm Long CNC Tool For Alu, zinc, copper. Rod: tungsten steel hard alloy. Aluminum alloy, zinc alloy, copper, aviation aluminum and other metal materials. Applicable machine: CNC machining center, engraving machine, precision engraving machine and other high-speed machines. DLC coating has high hardness and high wear resistance. More wear-resistant than uncoated, 4-5 times longer service life. 0.6um micro particle tungsten steel hard alloy. Micro-grain tungsten steel base material is used, which has higher wear resistance and strength and is an exclusive milling cutter for high hardness and high speed cutting applications. Large core diameter is more stable. Large core diameter design under the condition of guaranteed cutting space, which greatly enhances tool rigidity and vibration resistance to reduce tool breakage. U-groove design for smoother chip removal. The new U-shaped groove design increases the chip space to avoid sticky tools and improve machining efficiency. Universal chamfering round shank. Easy to use, good compatibility, enhanced vibration resistance and cutting speed of milling cutters, tighter clamping and no slippage. According to your choice.
