DIY Tool Rock DTH Drill Bit Water Well Drilling Rig Pump Driller Borehole Drill Equipment CD85-270

 

 

DTH bits are paired with their corresponding hammers (by drilling hole diameter and spline configuration). Customers can customize their DTH bits in various ways, such as changing the tungsten carbide insert profile (spherical, ballistic, etc.), face profile (flat face, concave, convex, etc.), and flushing holes.

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.

 

Caibide BUtton Shapge

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.
