8-1/2inch 5 Blades Carbide Drill Bits Coal Mining Bits Matrix 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 tough, this bit adds weight, has a smooth torque response, and maintains higher penetration than the competition. Unlike conventional dual-phase rigs, this technology requires more weight even in soft rock and is generally durable, but slower, even in harder rock. Conventional multi-position drills also have an unstable torque response when subjected to extra weight.
