drill bits face shape selectionBit Face Shape SelectionBrief introductionDrop Center BitFor high penetration rates in soft to medium hard and fissured rock formations, Low to medium air pressures. Maximum hole deviation control.Concave FaceThe all-round application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good fishing capacity.Convex FaceFor high penetration rates m soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash. And many reduce the load and wear on the gauge buttons. But poor hole deviation control.Double Gauge FaceThis kind face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.Flat Face BitThis kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressure. Good penetration rates are resistance to steel wash. 
drill bits carbide button shape selectionCarbide button shape selectionBrief introductionDomed/Round ButtonDomed /Round Buttons are usually used as gauge buttons of DTH Bits. Suitable for very abrasive and very hard formations.Parabolic/Semi- Ballistic ButtonsParabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.Ballistic ButtonBallistic Buttons are 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 ButtonSharp Buttons are usually used as front buttons of DTH bits for soft formations where fast penetration rates are possible.Flat ButtonFlat buttons are usually used as protection buttons to reduce Near on rubbing surfaces of DTH Bits. 
Besides, we have a wide range of rock drilling tools for drilling projects, including DTH Hammer, DTH Bit(Hammer bit), RC Hammer, RC Bit, drill pipe; Overburden drilling systems, symmetrix system; retrac button bit, shank adapter, coupling sleeve, drill rod; tricone bits, drill collar etc.
