Product Description
Construction machinery parts 3"4"5"6"8 DHD/QI/Cop/Misson/SD DTH Hammer and DTH steel Bits for Mining/Water well DrillingOur tools are widelyused in different drilling applications including mining,quarrying, water well drilling, geotechnical industries and etc.
In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.
Competitive Advantage
• High grade tungsten carbide inserts
• Bit bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery and heat treatmentHammer Size(inch) | Bit Shank | Connection Thread | Suitable bit | Working pressure | Air consumption |

Product OverviewCarbide button shape selection:
1. Domed/Round Button Domed/Round Buttons are usually used as gauge buttons of DTH Bits, suitable for every abrasive and very hard formations.
2. Parabolic/Semi-Ballistic Buttons Parabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.
3. Ballistic Button Ballistic Buttons are usually used as front buttons of DTH Bits, suitable for medium abrasive and mesium hard formations. They can also be used as gauge buttons if the rock is soft.
4. Sharp Button Sharp Buttons are usually used as front buttons of DTH Bits for soft formations where fast penetration rates are possible.
5. Flat Button Flat buttons are usually used as protection buttons to reduce wear on rubbing surfaces of DTH bits. Company Profile
