Home Drilling Equipment Drilling Tools Drag Bits

As well as supplying tricone rock bits, Dando can also supply drag bits- stepped, chevron and custom PCD types are available.

A drag bit is 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.
