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.

FAQ:

1. what is a button bit?
Tungsten carbide inserts rotate within the cones of button bits, also known as roller cones. Though producers still produce two cone and one cone bits, tricone, or three cone bits, are the most widely used.
2. How can one drill through large stones?
Drill for a minute while applying moderate pressure. Allow the drill to do the work; do not press the bit into the boulder. After taking the bit out of the hole, let it cool in the water pitcher. To cool the rock and remove dust, lightly mist it with water.
3. What about standard packaging?

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.
