The life of the DTH bit depends on the material and technology of the bit.        
The Yikuang Drilling ranges high quality rock drill bits is made of the most efficient high quality alloy steel. 
Use quality forged steel, heat treatment and shot peening to provide a durable and reliable balance of strength and toughness. 
1. Long life of bit: alloy steel material has a long service life, which is higher than similar products; 
2. High drilling efficiency: the drill teeth are wear-resistant, so that the drill bit can always be sharp, thus greatly improving the entering speed of the teeth; 
3.Steady drilling speed: the drill bit breaks the rock by scraping and cutting; 
4. Good spacing effect: the new diamond head has strong abrasion resistance and good spacing performance, which enables the cutting teeth to be utilized efficiently; 
5. Wide application range: it has been proved by practice that this drill bit is suitable for drilling in soft and medium hard formations, such as carbonate rock, limestone, cretaceous rock, clay rock, siltstone and sandstone (below grade 9 of drillability,). 
Compared with general drills, especially in rock formations of grade 6-8, the effect is especially remarkable. 
The submersible drill bit made by Yikuang Drilling ranges from 2 inches to 40 inches in diameter and has a variety of the most common end face shapes, alloy tooth styles and shank styles to match the application and rock formations you are drilling in. 
We can customize the drill bit according to your requirement.        
Different drill head shapes are selected according to different rock formations.
Bit face shape selection:
1. Drop Center 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.
