Exploration Drilling
Product description
Drag Bits are the perfect solutions for soil, sand, sticky clay,
and grouting drilling. They are designed for higher penetration
rates in softer unconsolidated formations, provide lower costs per
foot. Drag Bits are more aggressive than tricone bits, and have
higher speed while lower cutting action.
The Drag Bits can penetrate softer formations such as stiff clays
and mudstones very quickly. Usually used for construction or other
site investigation projects. It has two types, Step Type and
Chevron Type.

Application
The drag bit is designed for use in soft formations such as sand,
clay, or some soft rock.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.
Chevron-type drag bits are recommended for drilling in slightly
harder and more consolidated materials. Best suited for abrasive
conditions, Chevron-type drag bits are also available in a full
range of sizes from 3" up to 17 1/2".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.
