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
