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

 

 

 

Scope of application:

 

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