Product Description
PDC Concave Bit is a full-scale drilling bit, mainly be used in water well, geothermal well ,dam construction, coal mine gas, coal bed gas drilling.
It is suitable for soft to medium hard rock formation
The PDC bit is durable
1)Soft to medium formation drilling
Medium short parabolic profile with medium cutter density helps to obtain better ROP in soft to medium hard formation with lower compressive strength and small hard layers
2)Dura-set gauge
Gauge cutter promotes gauge wear resistance to provide long bit life
3)Hydraulics
Cuttings removal and bit cooling for bits are optimized by matching the volume of rock removed by the cutter on each blade with theproportionalfluid flow.
4)Unique back-rack design
The cutter’s back-rack has been unique design, reducing the bit torque and increasing aggressiveness.
