We can design and manufacture according to customer's requirements of the Bit Dia.,No.of air holes,carbide button shape and the face shape |
Our Bit Face Shape Selection |
Double Gauge Face--This kind of face shape is suitable for fast penetration rates in medium to hard rock formation.Designed for high air pressures and good resistance to steel wash step gauge bit.dth hammer drill bit / low air pressure tungsten carbide dth drill button bits |
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. |
Concave Face---The all-round application bit face specially for medium hard and homogenerous rock formations.Good hole deviation control and good flushing capacity. |
Flat Face---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. |
Drop Center---For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures.Maximum hole deviation control.dth hammer drill bit / low air pressure tungsten carbide dth drill button bits |
Our Carbide Button Shape Selection |
Spherical/Domed/Round Button are usually used as gauge buttons of DTH Bits, suitable for very abrasive and very hard formations. |
Parabollic/Semi-Ballistic Button are usually used as gauge buttons and front buttons of DTH Bits,suitable for medium abrasive and hard formations. |
Ballistic Button are usually used as front buttons of DTH Bits, suitable for medium abrasive and medium hard formations. They also can be used as gauge buttons if the rock is soft. |
Conical/Cone/Sharp Button are usually used as front buttons of DTH Bits for soft formations where fast penetration rates are possible and button breakage is minimal. |
