Wood drill

A wood drill bit, comprising:

• a clamping portion configured to be connected in a rotationally fixed manner to a tool receiver of a hand-held power tool;
• and
• a head portion provided with a centering geometry,
• wherein the clamping portion is located at a first end of the wood drill bit that faces away from a workpiece and the head portion is located at a second end that faces toward the workpiece,
• wherein the clamping portion is connected to the head portion via a shank portion,
• wherein a maximum outer radius of the head portion is greater than a maximum outer radius of the shank portion,
• wherein the head portion has at least one lip that comprises at least two steps for drilling a hole of a predefined inner radius into the workpiece,
• wherein an outer radius of a lip base of the at least one lip is less than 60% of an outer radius of the head portion,
• wherein a profile angle of between 10° and 30° is defined between the at least one lip and a perpendicular plane to a longitudinal central axis of the drill bit,
• wherein the at least two steps of the at least one lip are axially spaced apart from one another by one step height that is defined as a distance between adjacent steps of the at least two steps,
• wherein each of the at least two steps of the lip has a radial step width, and
• wherein the radial step width is greater than the step height,
• wherein the head portion has a helically coiled surface geometry, and
• wherein the helically coiled surface geometry defines at least one chip groove and at least one minor cutting edge.
