Dando|Drag Bits|for drilling operations

Dando design and supply drag bits – stepped, chevron and custom PCD types – as well as tricone bits.

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.
