Characteristics and advantages of DTH bit 
Long service life of drill bit: alloy rigid material has long service life and is higher than similar products; 
High drilling efficiency: the drill teeth are wear-resistant, which makes the drill bit always sharp, thus greatly improving the feed speed; 
Steady drilling speed: the drill bit breaks the rock by impact and shear; 
Good gauge keeping effect: the drill bit has strong wear resistance and good gauge keeping performance, which can make the cutting teeth be used efficiently; 
Wide application range: Practice has proved that this drill bit is suitable for drilling soft and medium hard strata such as carbonate rocks, limestone, chalk rocks, clay rocks, siltstones, sandstone, etc. Compared with ordinary drills, especially for drilling 6-8 rock strata, the effect is particularly remarkable.
Down-the-hole drill bits are mainly used in geological exploration, coal mines, water conservancy and hydropower, roads, railways, bridges, construction, etc.
