Abstract
A rotary tool (2) is provided, comprising: a main blade (4), a chip flute (6), a lateral surface (8), a flank (10) trailing the main blade (4) and extending from the main blade (4) up to the lateral surface (8) and to the chip flute (6), wherein the flank (10) comprises a kink (12) and is thus concave in configuration, wherein the kink (12) extends from the lateral surface (8) up to the chip flute (6) and thus divides the flank (10) into a leading partial surface (14) and a trailing partial surface (16). The invention further relates to a method for manufacturing such a rotary tool (2).
Claims13
A rotary tool comprising:
- a main blade;
- a chip flute;
- a lateral surface;
- and
- a flank trailing after the main blade and extending from the main blade up to the lateral surface and to the chip flute, wherein the flank comprises a kink and is thus concave in configuration, and wherein the kink extends from the lateral surface up to the chip flute and thus divides the flank into a leading partial surface and a trailing partial surface.
A method for manufacturing a rotary tool that comprises a main blade, a chip flute, a lateral surface, and a flank, wherein the flank is configured so as to trail after the main blade and extends from the main blade up to the lateral surface and to the chip flute, wherein the flank is configured with a kink and is thus concave, and wherein the kink is configured so as to extend from the lateral surface up to the chip flute and thus divides the flank into a leading partial surface and a trailing partial surface, the method comprising:
- ingraining the flank in a grinding step.
