drill bits face shape selection
|Bit Face Shape Selection||Brief introduction|
|Drop Center Bit||For high penetration rates in soft to medium hard and fissured rock formations, Low to medium air pressures. Maximum hole deviation control.|
|Concave Face||The all-round application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good fishing capacity.|
|Convex Face||For 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 Face||This 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 Bit||This 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 selection
|Carbide button shape selection||Brief introduction|
|Domed/Round Button||Domed /Round Buttons are usually used as gauge buttons of DTH Bits. Suitable for very abrasive and very hard formations.|
|Parabolic/Semi- Ballistic Buttons||Parabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.|
|Ballistic Button||Ballistic 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 Button||Sharp Buttons are usually used as front buttons of DTH bits for soft formations where fast penetration rates are possible.|
|Flat Button||Flat buttons are usually used as protection buttons to reduce Near on rubbing surfaces of DTH Bits.|
