Abstract
The invention relates to a method for producing a dental drill that has a shank () and a work section. The shank contains a centrally arranged, continuous first channel (). The work section contains one or more continuous, spiral-shaped further channels (). The first channel and the further channels open into a common chamber () connecting the shank and the work section. The shank is sintered with the work section in order to form a one-piece, sintered component that encloses the chamber connecting the shank and the work section.
