N&N Drilling - Roller & Drag Bits

Drag Bits can be used to drill any type of hole; they are the perfect solution for mud, sand, and sticky clay, as well as drilling out concrete or grout. Drag bits are also a more economical solution for seismic drilling. Chevron bits are designed for medium to hard formation and are used in areas that contain a lot of rock or drilling out concrete casing and plugs.
