Step Drag Bits

The 4 Wings Step Drag Bits are expertly designed to provide superior performance in soft to medium-hard unconsolidated formations, offering enhanced stability and cutting efficiency due to their four-wing configuration. Each feature contributes to the bit’s robust construction and reliable operation in challenging drilling environments.

• A solid one-piece heat-treated 4140 alloy steel body for bit strength & durability; the bit’s core is forged from a single piece of 4140 alloy steel, which undergoes specialized heat treatment. This process significantly enhances the overall strength and durability of the bit, ensuring it can withstand extreme drilling pressures and prolong its operational lifespan.
• CNC threaded machining for proper installation & use; precision is paramount for secure drilling, and the bit features advanced CNC threaded machining. This ensures perfectly formed threads, allowing for a tight, reliable connection to the drill string, which is crucial for preventing loosening and maintaining stability during aggressive drilling.
• Forgings are milled to better seat the carbide inserts. The structural components of the bit, where the cutting elements are placed, undergo meticulous milling. This creates precisely contoured seats that perfectly cradle the carbide inserts, ensuring they are optimally positioned and securely anchored for maximum cutting effectiveness and resistance to dislodgement.
• Select tungsten carbide inserts 5.5 mm thick are standard. To guarantee superior cutting performance and wear resistance, the bit is equipped with carefully chosen tungsten carbide inserts, each with a standard thickness of 5.5 mm. These robust inserts are designed to efficiently penetrate a variety of soft to medium-hard formations.
• Relief is hand-ground behind carbide inserts for maximum performance. A critical detail for optimal functionality, the area directly behind each carbide insert is skillfully hand-ground to create relief. This specialized shaping significantly improves chip evacuation, preventing material buildup and allowing the inserts to continuously engage the formation for peak drilling efficiency.

4 Wings Step Drag Bits offer enhanced stability and improved hole straightness compared to their three-wing counterparts, making them highly effective for drilling in various soft to medium-hard unconsolidated formations. Their design provides additional cutting surface and greater contact with the borehole, which contributes to their durability and efficiency in diverse applications.

These bits are particularly recommended across several industries where consistent performance and accurate hole drilling are paramount for project success:

• Mining: Ideal for drilling blast holes, exploration holes, and production in softer mineral deposits such as coal, gypsum, and salt. The four wings provide superior stability for straighter holes, optimizing blasting patterns and material extraction efficiency.
• Exploration: Utilized in geological and mineral exploration for obtaining accurate core samples and establishing precise boreholes in unconsolidated overburden, sands, and clays. Their stability helps in maintaining verticality and improving data integrity.
• Environmental: Essential for environmental remediation and monitoring well installations, particularly in soft soils, sludges, and light aggregates. The extra wing enhances bit stability, which is crucial for preventing borehole collapse and ensuring precise well placement.
• Water Well: Widely adopted in water well drilling for penetrating diverse unconsolidated formations, including sand, gravel, and clay. The four-wing design provides better stability and helps reduce deviation, leading to more efficient and reliable water well construction.
• Geo Exchange: Highly effective for creating boreholes for geothermal ground source heat pump systems in softer geological strata. The increased stability of the four wings helps ensure consistent borehole integrity, which is vital for the long-term performance of the geoexchange system.
