Abstract
A drill bit for drilling a hard material includes a drill bit blade defining an axis of rotation and including a first side and a second side positioned respectively on first and second lateral sides of the axis of rotation. The drill bit blade further includes a blade tip point that is laterally biased relative to the axis of rotation, and a first blade edge and a second blade edge starting at the blade tip point and ending at the first side and second side, respectively. An angular bisector between the first and second blade edges is inclined at an angle relative to the axis of rotation.

A drill bit blade for drilling a material, the drill bit blade defining an axis of rotation, the drill bit blade comprising:
- a first side positioned on a first lateral side of the axis of rotation;
- and
- a second side positioned on a second lateral side of the axis of rotation;
- a blade tip point that is laterally biased by a length of lateral bias distance relative to the axis of rotation;
- a first blade edge starting at the blade tip point and ending at the first side;
- and
- a second blade edge starting at the blade tip point and ending at the second side,
- wherein an angular bisector between the first blade edge and the second blade edge is inclined at an angle of inclination relative to the axis of rotation.
A drill bit for drilling a material, comprising:
- a drill bit body;
- and
- a drill bit blade mounted onto the drill bit body, the drill bit blade defining an axis of rotation, and the drill bit blade comprising:
- a first side positioned on a first lateral side of the axis of rotation,
- a second side positioned on a second lateral side of the axis of rotation,
- a blade tip point that is laterally biased by a length of lateral bias distance relative to the axis of rotation,
- a first blade edge starting at the blade tip point and ending at the first side, and
- a second blade edge starting at the blade tip point and ending at the second side,
- wherein an angular bisector between the first blade edge and the second blade edge is inclined at an angle of inclination relative to the axis of rotation.
