Low-pressure down-the-hole drill bits are rock drilling tools designed for use with low-pressure down-the-hole drilling rigs. They are primarily used for efficient and stable drilling in low to medium hardness rock formations and are widely applied in various engineering fields such as mining and quarrying.
| Face Shape | Use Condition |
|---|---|
 |
The all-round application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good flushing capacity. |
|
|
For high penetration rates in soft to medium-hard with low to medium air pressures. Most resistant to steel wash, may reduce load and wear on gauge buttons, but poor hole deviation control. |
|
|
Suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates and resistance to steel wash. |
| Button Shape | Use Condition |
|---|---|
|
|
Usually used as gauge buttons of DTH Bits, suitable for very abrasive and very hard formations. |
|
|
Usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations. |
|
|
Usually used as front buttons of DTH Bits, suitable for medium abrasive and medium hard formations. Can also be used as gauge buttons if the rock is soft. |
|
|
Usually used as front buttons of DTH Bits for soft formations where fast penetration rates are possible and button breakage is minimal. |
|
|
Usually used as protection buttons to reduce wear on rubbing surfaces of DTH Bits. |
