Hard Rock Drill Bits DTH Drill Bits For Water Well Blasting Drilling

 

Products Parameters:

 

1. high and low air pressure down-the-hole drill bits

2. Face type: drop center bit/concave face/convex face/double gauge face/flat face bit

3. Carbide button shape: domed/round button parabolic/semi-ballistic button ballistic button sharp button flat button

4. Drill rock type: Granite, Marble, Limestone, Basalt, ect.

5. Project types: Blast holes, Quarry , Anchoring, Infrastructure, Geothermal holes, Well drilling,ect.

 

Description

 

1. Long life span: the wear-resist of tungsten carbides is 10-20 times higher compared with other similar materials, which greatly extends the life of the carbide bits;
2. High drilling efficiency: the high grade hardness of the carbides can always stay sharp, which could increase the drilling speeds too;
3. New Diamond's bits are widely used in different rock formations like carbonate rock,limestone,chalk rock, clay rock,siltstone and sandstone;
4. It can greatly reduce the drilling cost, because of its high drilling speed and life span, which reduces the times to changes bits in the drilling service.

Advantage:

 

1. Advanced technology

2, High grade steel as material

3. Quik delivery

4. Large quantity are available

 

Bit face shape selection:
1. Drop Center Bit
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.
2. Concave Face
The all-round application bit face specifically for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.
3. Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.
4. Double Gauge Face
This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.
5. Flat Face Bit
This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.

Domed / Spherical Button

Domed / Spherical Buttons are usually used as gauge buttons of DTH Bits, suitable for very abrasive and very hard formations.

Parabolic / Semi - Ballistic Buttons

Parabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.

Ballistic Button

Ballistic Buttons 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.

 Sharp Button

Sharp BUttons are usually used as front buttons of DTH bits for soft formations where fast penetration rates are possible and button breakage is minimal.

 Flat Button

Flat buttons are usually used as protection buttons to reduce wear on rubbing surfaces of DTH bits.
