Claims
- 1. A wood bit comprising:
- a driving end;
- a driving end;
- a shank connected to said driving end;
- a blade attached to said shank, said blade having a pair of parallel opposite faces connected by a pair of outer sides being generally parallel to said shank;
- a pair of lateral shoulders extending inwardly from said outer sides and converging at a central point to form a leading end of said blade;
- a continuous cutting edge forged along the leading end of said blade, wherein a blade portion is forwardly bent in the direction of rotation, wherein each of said lateral shoulders is thereby forwardly bent from said respective outer sides through said central point.
- 2. The wood bit of claim 1, wherein said continuous cutting edge forms an axial rake angle extending along said lateral shoulder at about 15 seconds with respect to a plane perpendicular to said parallel opposite faces of said blade.
- 3. The wood bit of claim 1, wherein said continuous cutting edge has a beveled cutting edge.
- 4. The wood bit of claim 1, wherein said central point extends axially and upwardly from said leading end, having a pair of central point sides converging at a central point tip, wherein said central point is twisted in the direction of rotation.
- 5. The wood bit of claim 1, wherein said blade has a pair of cutting spurs projecting upwardly from said lateral shoulders of said blade, said cutting spurs located at a pair of locations where said lateral shoulders intersect with said outer sides, wherein each of said cutting spurs is forwardly bent in the direction of rotation so as to be in a coplanar relationship with said continuous cutting edge.
- 6. The wood bit of claim 1, wherein said pair of outer sides are slightly tapered downward away from said leading end.
- 7. The wood bit of claim 1, wherein said pair of outer sides are beveled to form an outer side cutting edge.
