Design & Manufacturing
- Materials: High-quality alloy steel with premium tungsten carbide buttons
- Durability: Designed to withstand heavy impact drilling and abrasive rock formations
- Optimized button arrangement: Improves energy distribution, maintains hole straightness, and reduces vibration
DTH Drilling System Advantages
In DTH systems, the hammer sits directly behind the bit, transferring impact energy efficiently to the rock surface. This design minimizes energy loss and boosts productivity compared to conventional methods.
