concave drill bit benefits
- Superior Hole Straightness: The dished face design naturally guides the bit, ensuring excellent directional control and minimizing deviation. This is crucial for precise blasting patterns, long production holes, or accurate reaming operations.
- Optimal for Harder Rock: These bits perform exceptionally well in medium to hard and abrasive rock formations. Their stable cutting action reduces wear and tear on the bit, offering prolonged service life even in challenging ground.
- Reduced Deviation: The inherent stability of the concave design significantly lessens the tendency for the bit to wander or “walk.” This results in more accurate boreholes, which is vital for maintaining drilling plans and reducing rework.
- Smooth Operation: The balanced cutting action and stability provided by the concave face lead to a smoother drilling process. This can reduce vibrations on the drill rig and improve operator comfort, contributing to overall efficiency.
Various Concave Drill Bit

Ideal for drilling in medium to hard and abrasive rock formations, their dished design ensures superior stability and controlled drilling, minimizing deviation. Our durable concave DTH bits deliver consistent, accurate boreholes, enhancing efficiency and reliability for your most demanding projects.
concave drag drill bit
We offer specialized concave drag drill bits, expertly designed for efficient drilling in soft, unconsolidated formations like clay, sand, and loose soil. Their unique concave cutting wings provide excellent hole cleaning and stability, preventing bit wander. These bits are ideal for water well drilling, geotechnical investigation, and shallow boreholes where rapid progress and effective material evacuation are crucial for project success.
Customize Your Desired Concave Drill Bit
Carbide Button Shape & Layout
We meticulously select and arrange carbide buttons on the concave face, optimizing their shape (e.g., domed, parabolic) and precise layout. This customization enhances bit stability and cutting efficiency in specific medium to hard rock conditions, ensuring superior hole straightness and minimizing bit wear for prolonged performance.
Flushing Hole Configuration
We tailor the number, size, and strategic placement of flushing holes within the concave face design. This optimization ensures efficient evacuation of rock cuttings, preventing re-grinding and maintaining consistent penetration rates. Effective flushing is critical for reducing bit wear and preserving hole integrity, especially in sticky or fractured formations.
Gauge Row Reinforcement
We customize the gauge rows of the concave drill bit with additional wear-resistant features or specialized carbide inserts. This reinforcement significantly extends the bit’s service life, particularly in abrasive or fractured ground, by protecting the critical outer diameter. It ensures the drilled hole maintains its precise size from start to finish.
Face Depth & Curvature
While maintaining the core concave principle, we can subtly adjust the depth and exact curvature of the bit face. This fine-tuning allows us to optimize the balance between penetration rate and hole straightness for specific rock hardnesses or drilling requirements, providing a tailored solution for your project’s unique geological challenges.
Concave Drill Bit vs Convex
Concave Drill Bit
Face Design: Features an inward-curving (dished) face, often with a pilot point in the center.
Primary Strength: Excellent for achieving and maintaining superior hole straightness and precision.
Ideal Rock Type: Best suited for medium to hard, consistent rock formations where accuracy is critical.
Drilling Action: Stably grinds and crushes rock, promoting a true and controlled drilling path.
Penetration Rate: Offers a good, consistent penetration rate, prioritizing accuracy over aggressive speed.
Face Design: Features an outward-curving (domed) face, providing a more aggressive leading edge.
Primary Strength: Excels in achieving high penetration rates and rapid rock breaking.
Ideal Rock Type: Best suited for soft to medium-hard rock formations where drilling speed is the primary goal.
Drilling Action: Aggressively bites into and fractures rock for fast progress.
Hole Straightness: Can be more prone to deviation, especially in varying or fractured ground, compared to concave designs.
