Product Description

120mm QL40 High Air Pressure DTH Drill Hammer Bits for Underground Drilling

Product Description

KINGDRILLING hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. 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.

Advantages of DTH Drill Bits:

1. Efficient Penetration: DTH drill bits are known for their high drilling efficiency, allowing for rapid and precise penetration into various types of rock formations. This efficiency is crucial in industries where time is of the essence, such as mining and construction.

2. Versatility: DTH drill bits are versatile tools that can be used in a wide range of applications, from soft to hard rock formations. Their adaptability makes them essential for drilling projects that require varying drilling conditions.

3. Enhanced Durability: DTH drill bits are constructed using high-quality materials that provide exceptional durability and resistance to wear and tear. This durability ensures a longer lifespan for the drill bits, reducing the need for frequent replacements.

4. Improved Hole Quality: These drill bits are designed to produce clean and precise boreholes, minimizing the need for secondary operations or additional rework. The high-quality holes created by DTH drill bits contribute to overall drilling efficiency.

5. Cost-Effectiveness: Despite their initial investment cost, DTH drill bits offer long-term cost savings due to their durability and efficiency. The reduced downtime and maintenance requirements associated with these drill bits translate to lower overall operational costs.

How to choose the suitable head face of the DTH drill bit?

1.  Concave:

Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful.

1.  Convex: 

Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate.

1.  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.

Product Application

It is suitable for drilling water wells, geothermal wells, short mircopiles,medium mini-type grouting hole of building, diamond harbour project.
