    Step-Type Drag Bits


    Step-type drag bits come in a variety of wing counts, steps, and sizes to accommodate drilling in a variety of formations, from sand and clay to shale, limestone, gravel, and more.

    Product Specifications

    • 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

    Three-Wing and Four-Wing - Three-wing bits tend to drill faster, whereas four-wing bits are longer lasting, more durable, and drill a straighter hole.

    Regular Step and Heavy Step - Regular Step bits develop smaller cuttings, whereas Heavy Step bits are more durable and are used in harder formations. Heavy Step bits have longer and wider steps and contain larger carbide for cutting. The quantity of steps is largely determined by the size of bit.
