The life of the DTH bit depends on the material and technology of the bit. Our drill bit 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 bit life: alloy steel material has a long life, higher than similar products;

2. High drilling efficiency: the teeth of the drill bit are wear-resistant, so that the bit is always sharp and the entry speed of the teeth is greatly improved;

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 range of applications: Practice has proved that the bit is suitable for soft and medium-hard formations such as carbonate rock, limestone, Cretaceous rock, clay rock, siltstone and sandstone (drillability lower than 9).

Compared with general drills, especially in rock formations of grade 6-8, the effect is especially remarkable.

The submersible drill bit is 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.

We can customize the drill bit according to your requirements. Different drill head shapes are selected according to different rock formations.
