Mission50 DTH Bit

 

With a wide selection of Mission50 DTH Bit , LEANOMS can accommodate any application. Each  Mission50 DTH Bit is constructed of high-quality alloy steel, which has undergone precision machining to make a flawless body, heat treatment to achieve the desired hardness, surface compression to increase fatigue resistance, and internal fabrication of precise buttons. These have been specifically designed for use with all sorts, hardnesses, and conditions of rock. The most crucial factors in choosing the best bit for a given application are bit life and rate of penetration.

 

Why Choose US:  

1. Adopt advanced heat treatment technology, product quality is stable, suitable for all kinds of rock.  

2. After many tests, the product life is at the top level in China.  

3. The product has excellent stability, and the adverse after-sale feedback of the product is less than 0.5%.

4. Our Mission50 DTH Bit can drill more effectively and wear better thanks to the appropriate bit head design.

5. Increasing Mission50 DTH Bit head processing can better protect the DTH Hammer by minimizing grinding of the hammer's front joint and extending the life of the DTH Hammer.

6. Adopt a circular gauge button and parabolic front button design, which improves stability and increases drilling efficiency.

Here are some more detailed comparisons between Mission50 DTH bits and typical DTH bits:

 

Material Composition:

Mission50: Uses a proprietary chromium-manganese-vanadium alloy with 12% chromium, 1.5% vanadium, and 0.8% carbon. Yield strength is 2000 MPa.

Typical bits: Often a basic carbon steel with 0.4-0.7% carbon, yield strength around 1500 MPa.

 

Cutting Element:

Mission50: Tungsten carbide composite with 93%WC, 6%Co, and 1% VC. Knoop hardness is 1800. Thickness is 30mm.

Typical bits: Tungsten carbide with 85-90%WC, 10-15%Co. Hardness of 1600-1700. Thickness of 20-25mm.

 

Impact Resistance:

Mission50: Withstands up to 350 Joules of impact energy per strike without damage based on testing.

Typical bits: Will fracture above 200 Joules of impact energy depending on shape/material.

 

Service Life:

Mission50: Average 300 drilling hours before replacement. Field tests show 3-5x longer than typical bits.

Typical bits: 60-150 drilling hours on average before wear cuts penetration rate in half.

 

Cutting Efficiency:

Mission50: Penetration rate of 1.5 m/min in medium granite. Reduces by less than 10% at end of life.

Typical bits: 1.0 m/min initial rate, drops 50% by 100 drilling hours in similar conditions.
