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 :
1) Drag bits are made according to API standard or no thread
standard just welding.
2) Various step and chevron drag bits are available from 3 inch to
17 1/2 inch. (normal small size are 3",3 3/4",3 7/8",4 3/4",4
5/8",5 7/8",8 1/2" to 17 1/2"and so on).
3) There is very good feedback from our customers because of the
quality and price.
4) Different drag bits can be made according to your drawings or
samples.
Drag bit are manufactured from forged high quality alloy steel and
PDC cutter insert, plus state of art welding technology and
multiple precision heat treatment to provide highest penetration
rate and longest lifespan at roughest condition.
Drag bits are designed for medium to hard formation and are used in
areas that contain a lot of rock and also in the oil field.
