<p>PROBLEM TO BE SOLVED: To provide an end mill and a processing method capable of reducing processing time and creating a convex structure.SOLUTION: An end mill 11 has a tooth point disposed on a tip end of the end mill 11, in which the tooth point is vertical to a long axis of the end mill 11. On the tip end of the end mill 11, a penetration part 17 whose radius is a value obtained by adding processing allowance to the radius of the convex structure, is provided. The end mill 11 is sent in a 1-axis direction for processing the convex structure.</p> |
