摘要： The present invention addresses the problem of making it possible to shorten as much as possible the distance from a major margin to a minor margin of a two-edge double margin drill in an axial direction and to keep the interval between the major margin and the minor margin within an ideal range. An interval (θ) between major margins (6) and respective minor margins (7), which are provided at outer peripheries of lands (5), are set at 80° to 100°, flank faces (8) both include a flat second flank face (8a) and a flat third flank face (8b), web thinning portions (4) including web thinning surfaces (4a) having convex arcs in a direction of drill rotation in front view of the drill are formed at a central portion of an end, and an outer end of each web thinning surface (4a) in a radial direction is disposed behind an end of the corresponding minor margin (7) in the direction of drill rotation and extends to the outer periphery of the corresponding land.

摘要： A drill includes a body. The body includes a first cutting edge, and a second cutting edge apart from the first cutting edge to the back end side relative to the first cutting edge and formed in a recess traversing an outer peripheral portion of the body. In a side view of the body in a first direction in which a distance between a center axis of the body and a first outer end of the first cutting edge is seen the longest, a second outer end of the second cutting edge is located at the center axis side relative to the first outer end of the first cutting edge.
