4 Wings Chevron Drag Bits

4 Wings Chevron Drag Bits are engineered to provide enhanced stability and durability when drilling in medium to hard, more abrasive formations. Their four-wing design, compared to three-wing counterparts, offers greater contact with the borehole, promoting straighter holes and reducing deviation. This makes them particularly effective in areas containing significant rock content or where concrete and plugs may be encountered.

The robust construction and precise manufacturing details of these bits ensure prolonged service life and consistent performance in demanding conditions.

• A solid one-piece heat-treated, 4140 alloy steel body for bit strength & durability; The bit’s foundation is a single, robust piece of 4140 alloy steel, uniformly heat-treated to achieve superior structural integrity and exceptional resistance to wear and tear, ensuring longevity even in harsh drilling environments.
• CNC threaded machining for proper installation & use; Utilizing advanced CNC machinery, the bit’s threads are precisely cut, guaranteeing a perfect, secure fit with the drill string. This precision minimizes wobbling and ensures stable, efficient power transfer during drilling operations.
• Forgings are milled to seat the carbide inserts better. The bit’s forged components undergo a meticulous milling process. This creates perfectly shaped pockets that tightly cradle each carbide insert, ensuring optimal alignment and secure retention, which enhances cutting efficiency and bit lifespan.
• Select tungsten carbide inserts 5.5mm thick are standard. High-grade tungsten carbide inserts, each with a consistent 5.5mm thickness, are carefully chosen for their extreme hardness and wear resistance. These inserts are strategically placed to maximize cutting action and extend the bit’s operational life.
• Relief is hand-ground behind carbide inserts for maximum performance. Skilled craftsmen hand-grind specific relief angles behind each carbide insert. This crucial detail facilitates efficient cuttings evacuation, preventing material buildup and allowing the inserts to consistently engage the formation for peak drilling performance.
