PDC Arc Drill Bit
for Water Well & Exploration
🔷 Product Overview
The PDC Arc Drill Bit is specially engineered for water well drilling applications, featuring an optimized arc crown structure that improves drilling stability and penetration efficiency. Equipped with high-quality PDC cutters (1308 / 1613 / 1913), this bit delivers excellent wear resistance and long service life in soft to medium-hard formations such as sandstone, shale, and limestone. Available in 3 blade, 4 blade, and 5 blade configurations, it ensures flexible adaptation to different drilling conditions.
Arc Crown Design
Smoother drilling, better stability, reduced vibration in water well & exploration.
High-Performance PDC Cutters
1308/1613/1913 options → faster penetration rate & superior wear resistance.
Optimized Hydraulic Structure
Efficient cuttings removal, anti-balling, and cooling for extended bit life.
Alloy Steel Body
42CrMo high strength, repairable, HRC 40–45 for durability.
API Standard Thread
2 3/8″ – 7 5/8″ API Reg, compatible with global drilling rigs.
Multi-Blade Design
3/4/5 blades adaptable to various formations from soft to medium-hard.
📌 Applications
Ideal for sandstone, shale, limestone, and other soft to medium-hard strata. The arc crown geometry reduces stick-slip, making it perfect for water well projects demanding high ROP and stable borehole quality.

⚡ Why Choose PDC Arc Over Traditional Tricone Bits?
50% Higher Drilling Efficiency
Continuous shearing action delivers faster ROP in soft to medium formations compared to rolling cone bits.
No Moving Parts → Lower Failure Rate
Eliminates bearing/seal failures. More reliable in water well and exploration drilling.
Longer Lifespan → Fewer Replacements
Premium PDC cutters and arc crown design extend bit life by 2-3x compared to tricone bits.
💡 Field proven: Operators using our PDC Arc bit have reported up to 40% reduction in cost per meter and significantly less tripping time in water well projects across Africa and South America.

❓ Frequently Asked Questions
Soft to medium-hard formations such as sandstone, shale, limestone, claystone, and medium-hard chalk. Not recommended for extremely hard granite or highly abrasive quartzite.
Absolutely. We offer 3,4,5 blades and cutter sizes 1308/1613/1913. Also support custom cutter grades and blade profiles based on your specific lithology.
The arc crown increases contact stability, reduces lateral vibrations, and provides smoother torque response – ideal for deeper water wells where hole deviation must be minimized.
Standard diameters (6”, 8½”, 12¼”) are usually in stock and ship within 5–7 days. Custom bits: 15–20 days. Worldwide shipping by air or sea.
Yes, we offer full OEM services including custom threads (any API or proprietary), laser logo engraving, and special hardfacing upon request.
