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.
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.
Chevron-Type Drag Bits
Chevron-type drag bits are recommended for drilling in slightly harder and more consolidated materials than step-type drag bits, such as hard shales, limestones, and unconsolidated gravels.

Replaceable Blade Drag Bit System
A replaceable blade drag bit system is the most cost-effective and versatile bit available.
Cost Effectiveness - The blade system allows you to replace a single blade when it is worn or damaged versus replacing the whole bit. Purchase multiple sets of blade types and sizes for much less than the cost of unitized bits. Keep a variety of blades on hand to ensure your time onsite is the most efficient.
Versatility - From 3 7/8" three-step bits to 6 1/4" four-step bits to the various sized chevron bits, this replaceable blade system offers versatility to meet your many different drilling needs
