- Product Description
94mm Four Wing Arc Angle Drill Bit – Advanced PDC Drilling Solution for Enhanced Performance and Extended Service Life
SHAANXI HAINAISEN INTELLIGENT EQUIPMENT MANUFACTURING CO.,LTD presents the 94mm Four Wing Arc Angle Drill Bit, an enterprise-grade PDC drilling tool engineered for superior performance across strata levels 1-12. This four-blade drilling solution features a precision arc angle design with four strategically positioned nozzles and premium 1308 PDC cutters, delivering exceptional durability and cutting efficiency. Manufactured in our 6,000 square meter facility by a team of over 150 professionals including 20 senior technicians, this bit combines over 10 years of drilling technology expertise with advanced multi-level force balance cutter arrangement. Available in sizes ranging from 60-165mm with 63.5 cone buckle connection (customizable), it offers reduced downtime and faster penetration rates for oil, gas, and mining applications.
Advanced Four-Wing Arc Design Technology
The innovative four-wing configuration of this drill bit maximizes contact efficiency with rock formations. Unlike traditional single-flute designs, the four-blade structure distributes cutting forces evenly across multiple tracks.
This layered tooth arrangement reduces energy consumption during penetration. Your drilling operations benefit from decreased torque requirements and minimized wear on individual cutters. The arc angle geometry enhances fluid dynamics throughout the drilling process, ensuring optimal cooling and efficient cuttings removal from the borehole.
The staggered, multi-level cutter layout creates balanced radial and circumferential load distribution. This engineering approach extends bit longevity while maintaining aggressive cutting action across varied geological conditions.
Selection & Comparison Guide
| Bit Type | Applicable Formations | Advantages | Limitations | Recommended Scenario |
|---|---|---|---|---|
| 94mm Four-Wing Arc Angle Drill Bit (Hainaisen) | f=6~12, mixed formations | High ROP, long life, good chip evacuation, low deviation | Slightly higher initial cost than basic bits | Coal mine gas drainage, medium-hard rock drilling, long-hole projects |
| Three-Wing Arc Angle Drill Bit | f<8, soft to medium formations | Faster ROP in soft rock, lower cost | Poor stability in hard/abrasive formations, prone to deviation | Soft coal seam drilling, shallow boreholes |
| Concave PDC Bit | Soft formations, high-speed drilling | Low cost, simple structure | Poor wear resistance, easy bit balling in sticky rock | Low-cost, short-term drilling in soft, non-abrasive formations |
| Spade Bit | Soft soil/coal, low-hardness rock | Ultra-low cost, easy to use | Very short life, poor chip evacuation, high deviation risk | Temporary, low-precision drilling in extremely soft conditions |
Selection Tips
- Choose the enhanced grade 94mm four-wing arc angle drill bit if your project involves hard rock (f>8) or abrasive formations
- For long borehole (over 50m) or deviation-sensitive projects, the four-wing arc design is recommended for better stability
- If your drilling is primarily in soft coal seams (f<6), consider the three-wing arc angle bit for higher cost-effectiveness
- For mixed formations with both soft and hard layers, the four-wing arc angle bit is the most balanced choice to avoid frequent bit changes
Versatile Application Across Multiple Industries
This drilling solution serves diverse sectors including oil and gas exploration, coal mining, and general mining engineering. The strata compatibility range of 1-12 makes it suitable for challenging geological conditions.
Whether you're drilling exploration wells, development wells, or mining boreholes, this bit adapts to your specific requirements. Customization options for connection types accommodate various drilling rig specifications and operational preferences.
The bit performs effectively in both rotary drilling and directional drilling applications. Its durability reduces the frequency of bit changes, particularly valuable for deep drilling projects where tripping time represents significant operational costs.
Superior Cutting Performance with PDC Technology
Our 94mm Four Wing Arc Angle Drill Bit utilizes polycrystalline diamond compact cutters that deliver exceptional hardness and thermal stability. The 1308 PDC cutter configuration provides superior cutting power compared to conventional tricone bits.
High-strength welding techniques secure cutting elements to the steel body, creating a robust tool capable of withstanding extreme downhole conditions. Pre-cutting and calibrating inserts protect main PDC cutters while performing initial rock destruction.
You'll experience faster penetration rates in formations ranging from soft sandstone and mudstone to harder limestone and crystalline rock. The optimized cutter exposure angles reduce the volume of broken rock, streamlining the drilling process and improving overall efficiency.
Enhanced Stability and Fluid Management
The four-wing structure significantly improves drilling stability compared to alternative designs. This geometric advantage reduces vibrations, minimizes bit whirl, and prevents stick-slip phenomena that can damage cutters.
Four strategically positioned nozzles create optimal hydraulic flow patterns. Proper fluid circulation cools the bit effectively while transporting cuttings away from the cutting face. This prevents bit balling—a common issue that reduces drilling efficiency and accelerates wear.
Your operations maintain consistent performance even in deep drilling environments. The balanced design ensures controlled penetration without compromising hole quality or directional accuracy.

Project Case Studies
A coal mining operation in Northwest China implemented our four-wing arc angle bits for geological exploration drilling. The project required penetrating alternating layers of sandstone, mudstone, and coal seams at depths exceeding 800 meters.
Previous conventional bits required replacement every 120 meters due to excessive wear. After switching to our 94mm Four Wing Arc Angle Drill Bit, the average bit life extended to 350 meters—a nearly 200% improvement. Penetration rates increased by 35%, reducing overall project completion time by three weeks.
An oil exploration company utilized these bits for formations characterized by interbedded hard and soft layers. The balanced cutter arrangement prevented premature failure that had plagued their previous tooling. They reported consistent performance throughout each run with minimal vibration issues, resulting in smoother boreholes and reduced post-drilling remediation costs.

FAQ:
Q1: What distinguishes the arc angle design from conventional flat-face bits?
A: By dispersing cutting forces more uniformly, the arc angle geometry maximizes cutter interaction with the formation. This improves fluid flow around the bit face and lessens the concentration of stress on particular cutters, increasing cleaning effectiveness and longevity.
Q2: How can I choose the right stratum rating for my application?
A: You can tailor bit parameters to your geological circumstances with the assistance of our technical experts. Harder formations (layers 7–12) benefit from greater cutter support and regulated exposure angles, but softer formations (strata 1–6) typically need more aggressive cutter exposure.
Q3: Can my drilling equipment's connection type be changed?
A: Yes, we offer customisation to meet your unique rig requirements, even tho our typical setup has a 63.5 cone buckle. During the ordering process, provide your connection specs to our engineering staff.
Q4: Which characteristics of the drilling fluid are ideal for this bit?
A: For efficient cooling and cutting transportation, maintain the right viscosity and solids content. Adequate cooling should be provided by your drilling fluid without producing excessive hydraulic forces that could harm your cutter. Based on your unique drilling parameters, we may offer comprehensive fluid recommendations.
Q5: In terms of cost-effectiveness, how does this compare to tricone bits?
A: PDC Bits, such as our four-wing type, usually drill three to five times longer than tricone bits, but the initial cost may be higher. For the majority of applications, lower cost-per-meter drilled is the result of shorter tripping times, fewer bit changes, and faster penetration rates.
