Abstract
A drill bit includes a body having a first end, a second end, an axis of rotation defined through the first and second end, and a body flute that extends along the axis of rotation at a helix angle. The drilling tool also includes a cutting head attached to the second end of the body. The cutting head includes a first land, a second land, and a cutting head flute. The cutting head flute is defined between the first land and the second land. The cutting head flute extends along the axis of rotation at the helix angle such that the body flute and the cutting head flute form a continuous flute.
Claims20
A drill bit comprising:
- a body including
- a first end,
- a second end,
- an axis of rotation defined through the first end and the second end, and
- a body flute that extends along the axis of rotation at a helix angle;
- and
- a cutting head attached to the second end of the body, the cutting head including
- a first land,
- a second land, and
- a cutting head flute defined between the first land and the second land, the cutting head flute extending along the axis of rotation at the helix angle such that the body flute and the cutting head flute form a continuous flute.
A drill bit comprising:
- a body including a first end, a second end, and an axis of rotation defined therethrough;
- and
- a cutting head attached to the second end, the cutting head including
- a bottom end that is attached to the second end of the body,
- a top end opposite the bottom end, and
- a land having a leading cutting edge and a trailing cutting edge, each of the leading cutting edge and the trailing cutting edge extending between the top end and the bottom end of the cutting head and helically around the axis of rotation.
A method of manufacturing a drill bit comprising:
- forming a body having a first end, a second end, an axis of rotation defined through the first end and the second end, and a body flute that extends along the axis of rotation at a helix angle;
- forming a cutting head including a first land, a second land, and a cutting head flute defined between the first land and second land, the cutting head flute extending along the axis of rotation at the helix angle;
- and
- attaching the cutting head to the second end of the body such that the body flute and the cutting head flute form a continuous flute.
