The down-the hole drill bits are typically paired with DTH impacters, which perform difficult drilling tasks that require plines and impacters. The DTH hammer bit has the advantages of straight drilling, fast drilling speed, and deep-hole drilling. To satisfy the diverse needs of customers, we supply a large number of down-the hole drill bits that are widely used in mining, engineering projects, and much more.

Advantages:

The down-the hole drill bits produced by XINLE are made from YG11C tungsten carbide, which have more buttons and the service life of the bits can increase by more than 15%.

The down-the hole drill bits are produced with large diameters, which give the bits higher wear resistance. Customers can customize the most suitable bits according to different hardness of rocks.
