(1) Wear pads, back reamer buttons, and or buttons on the pilot can be added for an additional fee.
(2) The ability to use less powerful equipment than that required to drill the large diameter hole.
(3) Straighter holes result from the smaller pilot hole.
DTH bits for hole opener :
1.Manufacture as your requirement
2.Bit diameter, face shape
3.Carbide button shape
4.Number of air hole.
Application: Mining, Quarrying, Tunneling, Construction, Geological Exploration, Water-well Drilling, Oilfield & Gas Industries.
Quality: More than 40 Years engineer to make sure the quality, 100% inspection
Carbide Button: Spherical, Ballistic, Semi-ballistic.
Bit face: Convex, Flat, Drop Center.
Color: Green, Blue, Grey, as your demand.
How to choose the suitable head face of the DTH drill bit? 1.Concave: Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful.
2.Convex: Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate.
3.Flat: Suitable for special hard formation stratum, especially for fracture, crack spacing and complex formation drilling effect is very good, has the good perpendicularity of the borehole.
Our Advantages as below:1. High quality steels materials. Steel is from TIMKEN and Tungsten carbide are YK05, or T6 from Element Six in Germany2. Kingdrilling DTH tools are forged by advanced electron-hydraulic forging hammer.3. Advanced heat-treatment equipment: multipurpose furnace heat treatment.4. Completed moulding (tooling ) departments with many molds available.5. Professional R&D team,completed quality system.6. Strict Quality-Check Systems.
