3. carbide button shape
4. number of air hole
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.
Shorter lifetime and susceptible to breaks : Conical Full Ballistic
Tungsten carbide life time. Semi Ballistic
Longer lifetime and less susceptible to breaks: Crown Point and Hemispherical
Head Profile Design
