Abstract
Embodiments of the disclosure provide a drill bit including a drill bit body having a central axis. A first cutting edge is disposed on the drill bit body at a first radial distance from the central axis as measured within a plane normal to the central axis. And a second cutting edge is disposed on the drill bit body at a second radial distance from the central axis as measured from within the plane. The first radial distance is less than the second radial distance.
Claims34
A drill bit comprising:
- a drill bit body having a central axis;
- a first cutting edge disposed on the drill bit body at a first radial distance from the central axis as measured within a plane normal to the central axis;
- and
- a second cutting edge disposed on the drill bit body at a second radial distance from the central axis as measured from within the plane, the first radial distance being less than the second radial distance.
A cutting tool comprising:
- a shaft with a first end for engaging a tool holding system and a second end for engaging a part;
- a first cutting flute having a first cutting edge disposed on the shaft at a first distance from a shaft centerline;
- and
- a second cutting flute having a second cutting edge disposed on the shaft at a second distance from the shaft centerline, the first distance being less than the second distance, and the first cutting edge being longer than the second cutting edge.
A method of drilling and/or reaming a stack of dissimilar aircraft components comprising:
- providing a stack of aircraft parts;
- drilling or reaming a hole using a cutting tool comprising:
- a first cutting flute having a first cutting edge disposed on the cutting tool at a first distance from a shaft centerline;
- and
- a second cutting flute having a second cutting edge disposed on the cutting tool at a second distance from the shaft centerline, the first distance being less than the second distance, and the first cutting edge being longer than the second cutting edge.
An apparatus for forming a hole comprising:
- a drill bit adapted for orbital movement about an orbital center, and adapted for rotation about a drill bit central axis;
- a first cutting edge on the drill bit disposed a first distance from the central axis as measured in a plane normal to the central axis;
- and
- a second cutting edge on the drill bit disposed a second distance from the central axis as measured in the plane, the first distance being less than the second distance.
