Abstract:
A drill has a thinning rake face formed in the front end. An intersection ridgeline between the thinning rake face and the tip flank face is the thinning edge. On the opposite side of the rotation direction, the first and second thinning wall surfaces ( 6 b,  6 c ) and are formed. Viewed from the front, an intersection angle between the thinning edge ( 4 a ) and the first thinning ridgeline is larger than 95°. The second thinning ridgeline (L 2 ) is bent to the opposite side of the rotation direction. The thinning edge and the first thinning ridgeline are connected via a concave curve line. The first and second thinning wall surfaces are connected via a concave surface, and a curvature radius of the concave curve line is smaller than a curvature radius of the concave surface.

Claim (Index 4):
The drill according to  claim 1 , wherein\n a coolant hole has an opening on the tip flank face, and at least one of the first thinning ridgeline and the second thinning ridgeline intersects the opening of the coolant hole.
