DTH Bit Profile

Matching the insert to the job requirements is essential in achieving the desired results. Each of the following buttons is ideal for different ground conditions, abrasion levels, PSIs and penetration levels. In general, the larger the number of gauge buttons the better overall performance, especially in hard rock.

Drill Bit Head Designs     潜孔钻头头部设计

 

                                      

CONVEX         FLAT FACE         CONCAVE       EXTRA GAUGESUPPORT

 

CONVEX(凸面)

Suitable for most drilling applications, particularly hard, abrasive rock to give a combination of speed and good service life.

 

FLAT FACE(平面):

Used for general purpose drilling, the flat face design is considered effective in very broken ground as well as hard formations that tend to overdrill

 

CONCAVE(凹面):

The concave bit design is an excellent all around bit, suitable for soft and hard formations.  The cone shaped face design provides good stability during drilling, allowing for straighter holes while reducing equipment vibration.  The carbide configuration design gives added penetration in many formations.

 

EXTRA GAUGESUPPORT(额外多齿钻头):

Providing similar performance to the concave bit design, the Extra Gauge Support is designed to provide excellent guage row carbide protection in highly abrasive and hard formations.  The design also gives added guage row protection while drilling through rock seams and changes in rock hardness.

 

Tungsten Carbide Insert Designs  (碳化钨硬质合金襄齿设计)

 

                            

DOME           BALLISTIC     PARABOLIC      CONICAL      DOUBLE DOME

 

DOME(圆齿):Tough shape for hard abrasive rock and deep hole drilling. Can be used in all applications.

 

BALLISTIC(弹道齿):

Big chip producer.  Ideal for less abrasive sedimentary deposits where speed is vital.  Less suited to badly broken ground and hard rock.

 

PARABOLIC(抛物线齿):

A combination design to provide increased speed over the Dome design and with greater wear characteristics than Ballistic designs.  Less suited to broken ground.

 

CONICAL(圆锥齿):

Suitable for sedimen- tary and broken rock conditions.

 

DOUBLE DOME(双圆齿):

The design combines the toughness of the dome Carbide with an additional smaller dome that gives added wear as well as an increase in penetration rate due to the some what ballistic shape.
