Three Wings 3 Blades Step Drag Bits Chevron Drag Bits Step Bits
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
- "Chevron" type for medium hard grounds
Specification of three wings drag bit :
Drag bits are economical tools when drilling softer geological formations and shallower depths. Sinodrills is the biggest supplier of drag bits in China, we supply both step drag bits and chevron drag bits. Chevron drag bits are usually used for drilling more abrasive formations like soft sandstons and shales. Chevron drag bits are more durable than step drag bits because of cutting structuer, but penetrate more slowly. We offer a comprehensive range of step drag bits as below:
