Drill Bit Design
This flat face is suitable for drilling extremely hard rock formations and corrosive wall formations at high air pressures. When the bits are drilling, the faster the drilling speed, the less wear of the drill body.
This concave face is suitable for all rock formations, especially in medium-hard and homogeneous rock formations, the effect is good. The blast hole deviation is small, and slag discharge effect is good.
This convex face is suitable for low to medium pressure drilling of soft medium hard rock formations, and the drill block is not easy to corrode. The characteristics of this design are the low load of the side button, the wear is not badly, and the drilling speed is fast.
Double Gauge Face
This double-sided button face is suitable for drilling extremely hard rock formations at high air pressures. When the bits are drilling, the speed is fast, and the bit body wear will also be less.
When using low-medium pressure to drill soft-medium hard and fractured rock formations, to obtain fast rock drilling speed and less blast hole slope, this face shape is usually used.
