KINGDRILLING hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a spline drive for rotating the bit in the ground. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes. Our variety of Down the Hole (DTH) bits is manufactured using high quality materials to provide you with a fine balance between penetration capability and bit life.
Shank types:CIR76, CIR90, CIR110, CIR130, CIR150,CIR170,CIR200
DTH hammer bits hole diameter: 2", 3'', 4'', 5'', 6'', 8', 10", 12"(85mm-305mm).
How to order:
Shank Type + Head Diameter + Face Design + Button Shape
How to choose the buttons:
1. Domed/round buttons
Domes/round buttons are usually used as gauge buttons of DTH bits, suitable for very abrasive and very hard formations.
2. Parabolic 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 button are usually used as front buttons of DTH bits, suitable for medium abrasive and medium hard formations. They can also be used as gauge buttons if the rock is soft.
1. How to order the products?
A: Please send the inquiry with detail item description or with Model number.
2. 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.
3. Can I expect a quality products?
A: Yes. mature production technology ensuring the quality satisfy international request.
4. What is the materials?
Steel is 42CrMo, Alloy is from KD10BH from ZCCCT
5. Product feature
Kingdrilling DTH tools are forged by advanced electron-hydraulic forging hammer, and harness process is managed by multipurpose furnace heat treatment.
6. How to choose the suitable head face of the DTH drill bit?
Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful.
Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate.
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.
