Bit face shape options: 1. 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. 2. Concave Face The all-round application bit face specifically for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity. 3. Convex Face For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control. 4. Double Gauge Face This kind of 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. 5. Flat Face Bit This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash. Carbide button shape selection: 1. Domed/Round Button Domed/Round Buttons are usually used as gauge buttons of DTH Bits, suitable for every abrasive and very hard formations. 2. 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. 3. Ballistic Button Ballistic Buttons are usually used as front buttons of DTH Bits, suitable for medium abrasive and mesium hard formations. They can also be used as gauge buttons if the rock is soft. 4. Sharp Button Sharp Buttons are usually used as front buttons of DTH Bits for soft formations where fast penetration rates are possible. 5. Flat Button Flat buttons are usually used as protection buttons to reduce wear on rubbing surfaces of DTH bits.
