The diamond bit has a wide working range and can penetrate quickly even in softer rock with low bit weight. When the ground gets harder, the bit can add weight with a smooth torque response and maintain a higher penetration rate than the competition. This technology differs from traditional duplex bits, requiring higher weights to drill holes 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.
