KAT DRILLING
1 / 2
The DTH hammers are designed with advanced drilling theory, capable of delivering energy more efficiently and drilling faster with lower air consumption. Utilizing the finest steel and advanced manufacturing techniques, the hammer maintains stable performance and an extended service life, while also being easy to assemble and repair.
These tools are widely used for mining, quarrying, road construction (drilling and blasting), water well drilling, slope protection, and anchoring.
