Our Bit Face Shape Selection |
||
|
Drop Center---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 specially for medium hard and homogenerous rock formations.Good hole deviation control and good flushing capacity. |
|
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. |
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. |
|
 |
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. |
