PDC Arc Drill Bit for Water Well & Exploration
🔷 Product Overview
The PDC Arc Drill Bit is specially engineered for water well drilling applications. It features 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. Consequently, it performs exceptionally well in soft to medium-hard formations such as sandstone, shale, and limestone.
Furthermore, it is available in 3 blade, 4 blade, and 5 blade configurations. This ensures flexible adaptation to different drilling conditions.

⚡ 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
This eliminates bearing and seal failures. As a result, it is 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.🔥 Why Choose Our PDC Arc Drill Bit
Faster Drilling Speed
Reduce project time and rig operating costs.Lower Cost Per Meter
Longer service life means fewer bits and better ROI.Stable Performance

❓ Frequently Asked Questions
Soft to medium-hard formations such as sandstone, shale, limestone, claystone, and medium-hard chalk. However, it is not recommended for extremely hard granite or highly abrasive quartzite.
Absolutely. We offer 3, 4, and 5 blades, plus cutter sizes 1308/1613/1913. Additionally, we support custom cutter grades and blade profiles based on your specific lithology.
The arc crown increases contact stability and reduces lateral vibrations. It also provides smoother torque response. Therefore, it is 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. For custom bits, lead time is 15-20 days. Worldwide shipping by air or sea is available.
Yes, we offer full OEM services. For instance, we can provide custom threads (any API or proprietary), laser logo engraving, and special hardfacing upon request.
