Product Application

DTH drilling tool is widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering. it has the advantage of high flatness, smooth hole wall, high rigid of drill rod and hammer, independent of high axial thrust, no limit of drilling depth, low cost of devices and easiness to maintain. At the drilling hole of dia.105mm-dia.254mm, a plenty of the DTH drilling tools are used.

Future

1.Button bit is well known for its high wear resistance on medium-hard to hard abrasive rock formations (between 200 Mpa to 260 Mpa compressive strength).Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture.

2.Recommended for eliminating hole deviation

3.Widely used drifting and tunneling

4.Bit face design is ideal for medium-hard to hard abrasive rock

High Performance DTH Drill Bits and Button Bits in 57mm to 660mm with Carburized Steel and Carbide

Concave

For medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.

Convex

For high penetration rates in soft in medium-hard with low to medium air pressure. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but port hole deviation control.

Flat face

This kind of face shape is suitable for hard to very hard and abrasive rock formation in applications with high air pressure. Good penetration rates an resistance to steel wash.
