8-1/2inch 5 Blades Rock Drilling Bit Oil Well Drill Bit Steel Body
The diamond bit has a wide working range and can penetrate quickly even in softer rock where the bit is lighter in weight. When the ground gets harder, this bit adds weight with a smooth torque response and maintains a higher penetration rate than the competition. This technology differs from conventional dual-phase drills in that it requires more weight to drill even in soft rock and is generally durable, but slower, even in harder rock. Conventional multi-position bits also have an unstable torque response when exposed to extra weight.
