NUMA High Pressure button bits Water Welling Drill Bit

DTH bits are used for blasting hole drilling rig and DTH hammer ,mainly applied in Mining, Marble quarry or well drilling and other construction projects.

The application of DTH hammer  

1. The longer life of the drill: the alloy material, with longer using life which better than the similar products;
2. High drilling efficiency: the drill buttons are wear-resistant, so that the drill can always keep sharp, thus greatly improving the speed of drilling.
3. The drilling speed is stable: the bit is scraped and cut to break the rock.
4. Good performance: MSD bit has strong wear resistance, good diameter protection and can make the cutting teeth be used efficiently, can drill more meters.
5. The use of a wide range: the practice proves that the bit is suitable for carbonate rock, limestone, chalk, clay rock,
siltstone, sandstone and other soft and hard (9-grade drillability of rock, hard rock drilling), compared with normal bit,
especially drilling in 6-8 grade rock the effect is particularly significant.

There are four types of end face design for high wind pressure DTH bits: end face convex type,End face plane type, end face concave type and end face deep concave center type. Cemented carbide mostly adopts ball teeth, spring teeth or tooth distribution mode shared by ball teeth and spring teeth.

The DTH drill bit mainly used in geological exploration,coal mine,water conservancy and hydropower ,highway ,bridge,construction etc.

DTH Hammer Advatages
1. Fast drilling speed and low air consumption due to the special inner structure.
2. Smooth performance and long service due to high quality alloy steel materials and advanced processing technology adapted.
3. Low problem rate and easy to maintenance due to simple, reliable and easy assemble and disassemble inner structure of hammer.
4. Easy to depart bit from hammer due to multi—head thread connecting chuck and cylinder of hammer.
5. Interchangeable with DTH bit and drill pipe.
