Product Description

Material: Tungsten Carbide
Step-type drag bits with 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.
Three-Wing and Four-Wing Drag Bits
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 Drag Bits
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.

Replaceable blade drag bits are available on request.

Chevron Type Drag BIts:
Chevron type drag bits are desigined for harder, more consolidated formations such as hard shale or limestone, areas with rock, and for drilling out concrete casing and plugs. The chevron type drag bit does not penetrade as fast as the step type, but will cut harder formations.
