Product Features


Step type bits are the most common type of drag bit used widely for soft to medium formations. Step-type drag bits are very effective in drilling soft and unconsolidated material. They are available in a full range of sizes from 3" to 17 1/2".The design of step-type drag bits provides for fast drilling penetration and requires only moderate drilling weight for proper operation. A large center flushing hole is incorporated into our design for efficient removal of cuttings.
