Abstract
A wood-drilling device includes at least one drill shank, at least one drill tip, and at least one cutting body. The cutting body has at least one cutting wing, wherein at least one of the cutting wings has a cutting surface, which is arranged on a base side facing towards the drill tip. The cutting surface is formed by at least two mutually adjoining cutting partial surfaces which are angled away from a drill plane, oriented perpendicular to the rotation axis, in the direction of the drill shank and which are angled to each other at an angle and each have an angle to the rotation axis different from 0°.
Claims13
A wood drilling device for drilling a wood material, comprising:
- at least one drill shank configured to be clamped on a machine tool,
- at least one drill tip having a thread, and
- at least one cutting body (i) configured to cut the wood material, (ii) and defining a rotation axis,
- wherein the at least one cutting body has at least one cutting wing,
- wherein the at least one cutting wing has a cutting surface which is arranged on a base side facing the drill tip,
- wherein the base side is arranged in relation to an imaginary cylinder about the rotation axis, and
- wherein the cutting surface is formed by at least two cutting partial surfaces bordering one another, angled from a drill plane perpendicular to the rotation axis in the direction of the drill shank, the at least two cutting partial surfaces are angled at an angle to one another and each cutting partial surface has an angle other than 0° to the rotation axis;
- wherein the at least two cutting partial surfaces are formed as flat surfaces.
