Product specifications:

A 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 theycan 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.

There are two forms of drag bits:
- "Step" type for soft grounds
