INDUSTRY CHALLENGES

The rock drilling tool industry (drill bit industry), whose core business includes drill bits, drill rods, drill shanks, and connecting sleeves, is currently undergoing a transition from low-end mass production to high-end domestic substitution. The industry primarily serves extremely harsh working conditions such as mining, tunneling, and infrastructure construction.
 
Bottleneck in "domestic substitution" of special steel: The high-strength hollow steel (hollow steel) required for mid-to-high-end drill rods still lags behind top international brands (such as Sandvik and Atlas Copco) in terms of fatigue life and hydrogen embrittlement resistance.

CORE MATERIAL AND PROCESS FLAWS (HARD FLAWS)

Frequent "tooth chipping/breakage" in cemented carbide: Under high-frequency impact in complex, high-hardness rock formations (such as granite and quartzite), the ball teeth of drill bits often experience premature spalling or breakage due to insufficient toughness, thermal fatigue, or residual welding stress, directly leading to early failure of the drill bit.

THREADED CONNECTION "ADHESION AND EARLY FRACTURE"

Due to high-frequency heavy-load impact, insufficient thread fit precision or surface hardening layer depth at the drill bit and connecting sleeve can easily lead to stress concentration at the thread root, resulting in early fatigue fracture or "seizing (adhesion)" due to high temperatures.
 

HARSH WORKING CONDITIONS AND EXTREME WEAR

Limited Construction Efficiency (Low Cutting Speed):** In complex, fault-prone, or frequently jammed heterogeneous formations, unreasonable drill bit structure design (such as chip removal groove design and tooth density) results in slow drilling speed (cutting speed), significantly increasing unit energy consumption and working hours.

EXCESSIVE WEAR IN HIGH-HARDNESS, HIGH-ABRASIVE FORMATIONS

Faced with highly abrasive siliceous rocks, alloy drill bits experience excessive radial wear (becoming blunt), requiring frequent shutdowns for resharpening, severely impacting construction continuity.
 
 
 

INVOLUTION IN THE LOW-END MARKET AND MONOPOLIZATION IN THE HIGH-END MARKET

Low-end market suffers from vicious competition due to homogenization: The vast majority of small and medium-sized enterprises in China focus on producing low-to-mid-end, conventional drill bits. Low technological barriers lead to price wars (low-price bidding), resulting in extremely low profit margins and a lack of funds for R&D investment.

FOREIGN MONOPOLY IN THE MID-TO-HIGH-END MARKET

In the mid-to-high-end drill bit market, supporting deep mining, large tunnel boring machines, and high-pressure, high-power rock drills (such as high-power hydraulic rock drills), end-users, prioritizing stability and total cost per mille (CPM), remain highly dependent on imported brands.
 
 

OUR SOLUTIONS

  • High-Performance Materials and Surface Strengthening Processes

    Fine Grain/Gradient Carbide Ball Tooth Technology: Utilizing high-toughness ultra-coarse grain or functionally graded carbide, optimizing cobalt (Co) content distribution, and improving the impact toughness and thermal splitting resistance of the ball teeth, fundamentally solving the problems of tooth loss, chipping, and early spalling in extreme hard rock drilling.

    High-Strength Hollow Steel Integral Carburizing and Composite Heat Treatment: Selecting high-quality Cr-Ni-Mo alloy structural steel, introducing computer-controlled gas carburizing, integral quenching and tempering, and surface shot blasting strengthening processes, forming a perfect combination of a high-hardness, wear-resistant surface layer and a high-toughness core, significantly improving the fatigue life and hydrogen embrittlement resistance of the drill rod.

    Precision Thread Microstructure Optimization and Anti-Seizure Coating: Ensuring thread profile and fit accuracy through CNC precision cyclone milling, reducing stress concentration; chemical heat treatment (such as sulfur-nitrogen-carbon co-diffusion) or coating a solid self-lubricating anti-seizure layer on the surface of the drill shank and connecting sleeve threads to prevent thread adhesion (seizure) under high-temperature, high-frequency impact.
  • Digital Non-standard Customization and Geological Adaptation

    Based on "One Mine, One Policy" Rock Mechanics Adaptive Design: According to the client's mine's uniaxial compressive strength (UCS), quartz content, and rock abrasion index (CAI), finite element analysis (FEA) is used to simulate high-frequency stress wave transmission, customizing the drill bit tooth structure (e.g., crown shape, ball tooth diameter, and inclination angle).

    Computational Fluid Dynamics (CFD) Optimization of Slag Discharge Channels: Through computational fluid dynamics simulation, the location of drill bit flushing holes (water holes/air holes) and the volume of side chip removal channels (flow channels) are optimized to ensure timely removal of rock powder at high feed rates (ROP), preventing secondary wear and erosion.
  • Upgrading from "Selling Products" to "Managing Drilling Costs"

    Based on a business model that reduces CPM (cost per meter): Moving away from the single consumable sales model, we offer meter-based/monthly all-inclusive services with the core performance indicator of Cost Per Meter (CPM) or Total Cost of Ownership (TCO). This transforms the customer's procurement risk into a win-win situation for both parties.

    Digital Drill Bit Lifecycle Tracking and Predictive Regrinding: Utilizing RFID or laser marking technology combined with on-site data to create drill bit history cards, we dynamically track the cumulative drilling footage (meters) of each drill rod and bit. This establishes a critical wear early warning mechanism, guiding workers to perform intelligent drill bit regrinding in a timely manner, extending the overall service life.

    Rock drill-tool matching optimization in field conditions: We dispatch professional application engineers (AEs) to adjust the optimal impact pressure, feed pressure and rotation speed for high-power hydraulic rock drills or deep-hole down-the-hole drills with impact force used on site, so as to maximize the matching of tools and reduce the occurrence of stuck drills and broken rods caused by improper operation from the source.

CASE STUDY

Tapered drill rods kept breaking, causing losses for the customer. In response to the customer complaint, we provided a solution and handling plan.

In November 2024, a customer purchased H22*108mm*7-degree drill rods from our company. Multiple rods broke. Faced with the customer's complaint and the urgency of the situation, we convened a meeting that same day with company leaders and technicians to address the issue.
