Each of the flutes includes a cutting edge (186), a rake face (184), and a clearance surface (188). Each of the lands is convex-shaped and disposed between a pair of the flutes. The drill point includes axial relief surfaces (198). Each of the axial relief surfaces has a planar area, is distinct from the lands and borders (i) a distal portion (200) of one of the cutting edges, (ii) one of the lands, and (iii) one of the clearance surfaces.</p> |
