Chevron type for medium hard grounds. Chevron bits are designed for medium formations and are used in areas that contain a lot of rock and also in the oilfield for drilling out concrete casings and plugs. Chevron drill bits are used for drilling more abrasive formations like soft sandstones and shales.
