105mm Carbon Steel Mining And Construction Drilling DTH Drill Bit
Product Information:
DTH hammers transmit intensive impact energy with low energy loss.
This results in good rock breakage, high penetration rates and high
productivity. The equipment is designed to give optimal hole
quality, reliability, and long service life, as well as the best
blasting results and low total operation cost.
Applications:
• Underground mining
• Quarry benching operations
• Water well drilling
Advantages:
1. Advanced materials technology and optimized design provides high
productivity, great reliability and less operating costs
2. With improved air efficiency, fuel consumption is less.
3. High quality raw material ensures the top quality tools.
