Concave Face All kinds of rock formation.      especially for medium-hard and homogeneous formation. Convex Face soft to medium hard Drop Center Face soft to medium hard and fissured rock formation Carbide Button Shape Selection button shape Application Dome/Round Button Usually used as gauge buttons of DTH bits, suitable for very abrasive and hard formations. Parabolic/      Semi-Ballistic Button Usually used as gauge buttons and front buttons of DTH bits, suitable for medium abrasive and hard formations. Ballistic Button Usually used as front buttons of DTH bits,suitable for medium abrasive and medium hard formations. They can also be used as gauge buttons if the rock is soft. Sharp Button Usually used as front buttons of DTH bits for soft formations where fast penetration rated are possible and button breakage is minimal. Flat Button usually used as protection buttons to reduce wear on rubbing surfaces of DTH bits.
