CIR90 90mm Low air pressure Down The Hole Hammer Bit
 |
Concave Face | The all-around application bit face specifically for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity |
| Ballistic Button | Ballistic buttons are usually used as front buttons of DTH bits, suitable for medium abrasive and medium hard formation. They can also be used as gauge buttons if the rock is soft. |
 |
Concave Face | |
| Spherical Button | Spherical/Domed/Round Button Domed/Round Buttons are usually used as gauged buttons of DTH bits, suitable or very abrasive and very hard formations. |
 | Convex Face | For high penetration rates in soft to medium-hard with low to medium air pressure. It is the most resistance to steel wash, any may reduce the load and wear on gauge buttons, but poor hole deviation control. |
| Ballistic Button | |
 | Flat Face | This kind of face shape is suitable for hard to very hard and abrasive rock formation is applications with high air pressure. Good penetration rates and resistance to steel wash. |
| Spherical Button | |
| Face: | Flat Face, Concave Face, Convex Face |
| Tungsten Carbide: | Ballistic Buttons, or Spherical Buttons |
| Color: | Green or Based on Customer requirements |
In DTH hammers, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH hammers a nearly constant penetration rate regardless of hole length.
Applications
1. Underground mining
2. Quarry benching operations
3. Water well drilling
