Cutting tool with integrated lubrication

A cutting tool for machining mechanical parts, comprising:

• a tool body with a central axis (A) and a gripping diameter,
• a tool head adjacent to the tool body in a direction of the central axis (A) and comprising a sprinkling region and a cutting portion having a cutting diameter which is smaller than the gripping diameter,
• at least one lubrication duct extending through the tool body and opening into a sprinkling hole located in the sprinkling region, and
• a directional sprinkling ring for attachment to a ring connection region of the tool body, the ring connection region being adjacent to the sprinkling region, the directional sprinkling ring being configured in such a way that it delimits, with at least one portion of the sprinkling region, a distribution space, wherein a cross section of a portion of the distribution space defined between a conical portion of the directional sprinkling ring and a portion of the sprinkling region having the sprinkling hole, is continuously reduced in the direction of the cutting portion.
