  • Chevron Type Drag Bits Wholesale - China

    price: contact company for price

    A drag bit is a drill bit usually designed for use in soft formations

    such as sand, clay, or some soft rock. However, they will not work well

    in coarse gravel or hard rock formations. Uses include drilling water

    wells, mining, geothermal, environmental and exploration drilling.

    Whenever possible, they should be used to drill pilot holes because they

    produce cuttings that are easiest to log.

    Select tungsten carbide inserts 3/16' thick are standard

    Carbide inserts are individually hand soldered using nickel silver rod

    Bits fabricated are welded with high tensile strength 7018 rod

    Drag bits are welded solid at the nose for durability

    Blades originate from 4140 heat-treated tool steel forgings

    Forgings are milled to better seat the carbide inserts

    Relief is hand ground behind carbide inserts for maximum performance

    Bits can be built to the gauge tolerances required
