Other than PDC bits, drilling drag bits have the lowest cost per bit. Drilling drag bits are a rotary drill bit built with a steel body and tungsten carbide teeth.
These bits will out preform other more expensive bits if used appropriately. Drilling drag bits are extremely popular choice for seismic drilling, blast hole drilling and geothermal drilling applications. For best results adjust the rotational speed to 50% less than what you would normally use for a tricone bit of the same size and reduce the weight on bit by the same amount.
Description of drilling drag bit :
A drilling drag bit is simply a series of blades (usually three or four in number) which produce a shearing action when rotated. They are comparatively inexpensive due to the lack of moving
parts and they can penetrate softer formations such as stiff clays and mudstones very quickly.
The drag bit usually used in very soft to medium formation when the dth hammer as the tricone bit, lose of their effectiveness.
The cleaning of the hole is realized by the injection of air or water.

- "Chevron" type for medium hard grounds
