Specification of SD4 DTH Bits:
Bit Face Shape of SD4 DTH Bits:
1. Drop Center Face
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
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.
Carbide Button Shape of SD4 DTH Bits:
1. Domed/ Round Button
It is usually used as gauge buttons of DTH bits, suitable for very abrasive and very hard formations.
2. Parabolic/ Semi-ballistic Button
It is usually used as gauge buttons and front buttons of DTH bits, suitable for medium abrasive and hard formation
3. Ballistic Button
It is usually used as front buttons of DTH bits, suitable for medium abrasive and medium hard formations. It can also be used as gauge buttons if the rock is soft.
4. Sharp Button
It is usually used as front buttons of DTH bits, suitable for soft formations where fast penetration rates are possible.
5. Flat Button
It is usually used as protection buttons to reduce wear on rubbing surfaces of DTH bits.
