Carbide Selection


Carbide Designs

Perhaps the most fundamental decision when selecting different carbide

configurations is profile shape. Button bits most commonly have either a hemispherical

or semi-ballistic carbide design; however it is not uncommon to use other carbide designs as well.


Faster

Shorter lifetime and susceptible to breaks : Conical Full Ballistic


Penetration rate:

Tungsten carbide life time. Semi Ballistic


Slower

Longer lifetime and less susceptible to breaks: Crown Point and Hemispherical


Head Profile Design


Flat Face

Applications : Hard and abrasive formations, all round

Typical formations: Granite, hard limestone, basalt


Convex

Applications: Soft to medium hard rock, high penetration rate.

Typical formations : Limestone, hard limestone, shale, granite, basalt


Concave

Applications: Medium hard to hard formations, less abrasive, fractured formations, excellent control over hole deviation

Typical formations : Granite, basalt


Concave Kupa

Applications : Special design with ballistic front buttons, medium hard to hard formations, fractured formations.

Typical formations :Granite, basalt


Scope of application:


Mining, quarry, road building, well hole drilling, blasting, landslide prevention, dam reinforement, anchoring, geothermal, hydrology, etc
