Drag bits are created using top-quality alloy steel and hard alloy that have been forged, along with cutting-edge welding techniques and precise heat treatments. This combination ensures that these bits have the highest drilling speed and longest lifespan even in the toughest conditions.
Typically, drag bits are ideal for softer formations like sand, clay, or some types of soft rock. They may not be as effective in rough gravel or hard rock formations. These bits are commonly used in drilling water wells, mining operations, geothermal projects, environmental studies, and exploration drilling. It is recommended to use drag bits for pilot hole drilling whenever possible, as they produce easily loggable cuttings.
Three-wing drag bits are known for their faster drilling capabilities, while four-wing drag bits are preferred for their durability, longevity, and ability to drill straighter holes.
