Abstract: A rotary drag bit (110) includes a primary cutter row (143) comprising at least one primary" cutter (11) and a multiple backup cutter, group (153). T he multiple backup cutter group comprises a first and second trailing cutter row (154, 155), each comprising at least one cutter positioned to follow th e at least one primary cutter. The rotary drag bit life is extended by the m ultiple backup cutter group, making the bit more durable and extending the l ife of the cutters. Further, the cutters of the multiple backup cutter group are configured to selectively engage a subterranean formation material bein g drilled, providing improved bit life and reduced stress upon the cutters. Other embodiments of rotary drag bits are provided.
