High Air Pressure DHD350 5'' Inch Down The Hole DTH Hammer and Bit for Hard Rock Drilling
The life of the DTH bit depends on the material and technology of
the bit. The KSQ bit is made of the most efficient high quality
alloy steel.
Use quality forged steel, heat treatment and shot peening to
provide a durable and reliable balance of strength and toughness.
1. Long life of bit: alloy steel material has a long service life,
which is higher than similar products;
2. High drilling efficiency: the drill teeth are wear-resistant, so
that the drill bit can always be sharp, thus greatly improving the
entering speed of the teeth;
3. Steady drilling speed: the drill bit breaks the rock by scraping
and cutting;
4. Good spacing effect: the new diamond head has strong abrasion
resistance and good spacing performance, which enables the cutting
teeth to be utilized efficiently;
5. Wide application range: it has been proved by practice that this
drill bit is suitable for drilling in soft and medium hard
formations, such as carbonate rock, limestone, cretaceous rock,
clay rock, siltstone and sandstone (below grade 9 of
drillability,). Compared with general drills, especially in rock
formations of grade 6-8, the effect is especially remarkable.
The submersible drill bit made by KSQ ranges from 2 inches to 40
inches in diameter and has a variety of the most common end face
shapes, alloy tooth styles and shank styles to match the
application and rock formations you are drilling in.
We can customize the drill bit according to your requirement.
Different drill head shapes are selected according to different
rock formations.
