High Air Pressure DTH Drill Bits SP680

      DTH drill bits are mainly used in geological exploration, coal mines, water conservancy and hydropower, roads, railways, bridges, construction, etc.

Characteristics and advantages of DTH drill bits：

1. Long life of drill bits: alloy rigid material, its service life is long, and it is higher than similar products.;

2.  High drilling efficiency: the drill teeth are wear-resistant, so that the drill bit can always remain sharp, thus greatly improving the tooth inlet speed.;

3. Stable drilling speed: the drill bit uses impact and shear to break the rock;

4. Good diameter preservation effect: The Innovake drill bit has strong wear resistance and good diameter preservation performance, which can make efficient use of cutting teeth.;

5. Wide range of use: Practice has proved that the drill bit is suitable for soft and medium-hard (rock formations below grade 9 drillability,) hard formations such as carbonate rock, limestone, chalk, clay rock, siltstone, sandstone, etc., compared with ordinary drill bits, especially for drilling into rock formations of grade 6-8, the effect is particularly significant.;
