Features
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: strong abrasion resistance and good spacing performance, which enables the cutting teeth to be utilized efficiently;
Application
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.
The submersible drill bit from 2 inches to 18 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.
