Drag Bits
Drag bits generally are designed for use in softer formations of unconsolidated material such as clays, sands, shale, and soft limestone’s. They have a wide range of uses from geothermal and waterwell drilling to road construction, ground water, natural gas and everything in between.
There are several types of drag bits that each have they’re own purpose and are better at certain types of drilling than others. For example drag bits are not ideal for hard rock formations or coarse gravel; but their uses for exploration and environmental drilling are well documented and their most common job. They are especially useful for drilling pilot holes; as the cuttings they produce are easiest to log.
Step Type Bit: One of the most common type of drag bits used in the drilling industry; primary uses include soft to medium unconsolidated formations.

Chevron Type Bit: These are often used for medium to hard formations. They are often used to drill out concrete casings and plugs in the oilfield, and for harder formations containing larger amounts of rock. There are 3 way and 4 way Chevron bits designed for all types of drilling.
