KINGDRILLING DTH button bit description:
Down-the-hole hammers are used in conjunction with KINGDRILLING hammer bits to drill holes through a variety of rocks. Drill hammer bits are made with a spline drive to enable bit rotation in the ground when used with DTH hammers. Drill bits can drill a variety of hole diameters since they come in a variety of sizes and types. To give you a precise balance between penetration capability and bit life, our range of Down the Hole (DTH) bits is made using premium materials.
Maintenance is made simple and convenient with our DTH drill bit. Thanks to its user-friendly design, disassembly and cleaning processes are a breeze. This means less downtime and more productive drilling time. With regular maintenance, you can keep the bit in optimal condition, ensuring consistent performance throughout its service life.

FAQ:
1. What is button bit?
Button bits, or roller cones, have rotating cones that contain tungsten carbide inserts. Tricone, or three cone bits, are the most common; however, manufacturers continue to make two cone and one cone bits.
2. How do you drill through boulders?
Apply moderate pressure to the drill, and drill for one minute. Don't force the bit into the boulder; let the drill do the work. Remove the bit from the hole, and cool it in the pitcher of water. Lightly spray the boulder with water to remove dust and to cool the rock.
3. How about the common packing?
A: If there is no special packing demand, we will take it as our normal packing. First in small carton, and then put in the bigger carton together to make sure goods completed.
4. How to check the product are the exact one you want?
A: If possible, please attach one reference picture to avoid any misunderstanding or any links from our website for a better understanding.
5. How to choose the suitable head face of the DTH drill bit?
Concave:
Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful.
Convex:
Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate.
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.
