CONSTITUTION: A rough cut portion(30) is formed under a right cut portion(20). The diameter of the rough cut portion is smaller than the rough cut portion. A groove(40) is formed between the right cut portion and the rough cut portion. A web thickness is formed between a float(11) under the rough cut portion. A tip margin portion and a thinning portion are separated by a separating line. An endmill(50) having a flat cut portion(54) and a side cut portion(55) is formed by expanding the float(11).
