Product selling point
Advantages:
1. The long life of the drill: the alloy material, its service life is long, and higher than the similar products;
2, The drilling efficiency is high: the drill tooth is wear-resistant, so that the drill can always keep sharp, thus greatly improving the speed of the tooth.
3. The drilling speed is stable: the bit is scraped and cut to break the rock.
4. The effect is good: the new diamond bit has strong wear resistance, good diameter protection and can make the cutting teeth be used efficiently.
5. The use of a wide range: the practice proves that the drill is suitable for carbonate rock, limestone, chalk, clay rock, siltstone, sandstone and other soft and hard (9 - grade drillability of rock, hard rock drilling), compared with the general drill, especially drilling 6-8 grade rock the effect is particularly significant.

Bit face shape selection
1. Center drop Bit
For high penetration rates in soft to medium hard and fissured 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 homogenerous 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.
Carbide button shape selection
1. Domed/Round Button
2. Parabolic/Semi-Ballistic Buttons
3. Ballistic Button
4. Sharp Button
5. Flat Button
5" High Air Pressure DTH Bits
