Mission Series DTH hammer bits Mission 80

Mission Series DTH hammer bits Mission 80 :

A noticeable feature of dth Bits is that they have more buttons, which increases the energy released when drilling. The bits also include the global leader hard alloys, resulting in less wear, longer service life and fewer interruptions.With improved heat treatment and increased face hardness, the body is harder, tougher and sturdier. That means premium performance and longer service life。We can also provide the best solution for your mining, with higher efficiency and lower cost.

The following sizes are available for you to choose from, or to provide you with customized services

Advantages of down-the-hole drill bits

▲The longer life of the drill: Made from premium quality nickel-alloy steel for increased durability and wear characteristics, and YK 05 tungsten carbide which is same grade as internationally well-known brand.

▲High Drilling Efficiency: the drill buttons is wear-resistant,so that the drill can always keep sharp,thus greatly improving the speed of the drilling;

▲The drilling speed is stable:the bit is scraped and cut to break the rock;

▲Good performance:the HFD bits has strong wear resistace,good diameter protection and can make thecutting teeth be used effciently;

▲Quality is assured: Entire CNC processing procedure ensure the quality consistency and reliable.
