Description of carbide endmill cutter/end mill cutter or endmill cutter 1, Chip pocket wih unique shape exerts excellent performance even in slot and cavity machining. 2, Sharp cutting edge and large helical angel design effectively prevent built-up edge. 3, Anti-vibration design of whole edge can suppress the charttering during machining and improve surface quality. End tooth type of carbide endmill cutter/end mill cutter or endmill cutter 2-flute flattened end mills 2-flute ball nose end mills 2-flute R end mills 3-flute flattened end mills 3-flute R end mills 4-flute flattened end mills 4-flute ball nose end mills 4-flute R end mills 6-flute flattened end mills Machining operation of carbide endmill cutter/end mill cutter or endmill cutter flattened end mills for side machining flattened end mills for shoulder machining flattened end mills for straight slot machining flattened end mills for deep slot machining ball nose end mills for profile machining ball nose end mills for cavity machining ball nose end mills for slot machining ball nose end mills for deep slot machining R end mills for side machining R end mills for slot machining R end mills for profile machining
