KINGDRILLING DTH button bit description:

A variety of rock types can be drilled through using KINGDRILLING hammer bits in conjunction with down-the-hole hammers. Drill hammer bits include a spline drive to allow the bit to rotate 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.

Crafted with meticulous attention to detail, our DTH drill bit is built to last. Each component is carefully selected and manufactured from premium materials, ensuring excellent rigidity. This not only enhances drilling efficiency but also extends the lifespan of the bit, providing you with remarkable value for your investment.

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.
