Drilling tool

A process for producing a drilling tool, the process comprising:

• feeding a rotating grinding disk into a drill blank;
• forming a chisel edge;
• forming a curved major cutting edge which extends from the chisel edge in a radial direction of the drill blank;
• forming a thinned region near an end of the drill blank, via moving the grinding disk in a radial direction of the drill blank, wherein the thinned region extends to the chisel edge and the curved major cutting edge;
• and
• forming a chip flute which continuously adjoins the thinned region, via moving the grinding disk in a longitudinal direction of the drill blank;
• wherein said forming of the thinned region comprises:
• forming a portion of the chip flute, and an end of the chip flute, in the region of the chisel edge;
• and
• forming the thinned region to merge continuously, without any discontinuities, without any kinks, and without any ridges, into a remainder of the chip flute.
