Abstract:
Tungsten carbide drill bits for removing material from alloys and other hard materials are disclosed. A conventional drill bit is modified by removing material from the forward portion of the bit to increase the radius of the cutting edge. The drill bit is then coated with a nanostructured diamond film using a chemical vapor deposition process.
