China high air pressure mining button 152mm hard rock dth hammer water well drill bits
Down the hole bits advantage
1. The longer life of the drill : longer using life
2. High Drilling Efficiency : the drill button is wear -resistant ,so that the drill can always
keep sharp ,thus greatly improving the speed of the drilling
3.The drilling speed is stable : the bit is scraped and cut to break the rock
4. Good perforemance
5.The use of a wide range : 9-grade drillability of rock,hard rock drilling

Bit face shape selection:
China high air pressure mining button 152mm hard rock dth hammer water well drill bits
1. Drop Center Bit For high penetration rates in soft to medium hard and corrosive rock formations. Low to medium air pressures.Maximum hole deviation control.
2. Concave Face
The all-round application bit face specifically for medium hard and homo generous rock formations. Good hole deviation control and good flushing capacity.
3. 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.
4. Double Gauge Face
This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.
5. Flat Face Bit
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.
