Diamond bits have a wide working range and can penetrate quickly even in softer rock with a 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. The technology differs from traditional duplex bits in that it requires higher weight to drill even in soft rock and is generally durable even in harder rock, but is slower. Conventional multi-position bits also have an unstable torque response when exposed to extra weight.
