Drag bits are designed for a variety of applications including
seismic exploration, soil sampling, mining and construction.Drag
bits are used for drilling in 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 3-7/8” to 12-1/4”.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.

harder and more consolidated materials. Best suited for abrasive
conditions, Chevron-type drag bits are also available in a full
range of sizes up to 8”.The clean design, use of premium tungsten
carbide and rugged construction of these fine drilling tools
ensures effective performance in a variety of ground conditions.
