Diamond DTH Drill Bit
🔩 30% Lower Cost
⏱️ 20% Higher Efficiency
📏 90–203mm Sizes
When drilling in granite, basalt, quartzite, or other high-strength rock formations, ordinary DTH bits wear out quickly — leading to frequent replacements, downtime, and increased operational costs.
Our Diamond DTH Drill Bit is engineered specifically for hard and abrasive rock formations. With industrial-grade diamonds embedded into the drilling crown, it delivers superior cutting strength, outstanding wear resistance, and extended service life.
Whether in mining, construction foundation drilling, geothermal exploration, or water well drilling, this bit is designed to maximize efficiency and reduce total operational cost.
Product Overview
The Diamond DTH Drill Bit combines:
- Industrial-grade diamond cutting elements
- Optimized crown structure
- High-strength alloy steel body
- Precision air hole configuration
The diamond-reinforced crown significantly improves abrasion resistance and impact durability, ensuring stable performance under extreme down-the-hole hammer conditions.
Its optimized design enhances:
Why Choose Diamond DTH Drill Bits?
1️⃣ 6X Longer Service Life
Compared with conventional DTH bits, the diamond-enhanced structure increases service life by more than 6 times in hard rock formations. This dramatically reduces:
- Bit replacement frequency
- Non-productive downtime
- Operational interruptions
2️⃣ 30% Lower Overall Tool Cost
Although the initial purchase price may be higher, the extended lifespan significantly lowers:
- Cost per meter drilled
- Labor replacement cost
- Equipment idle time
Total operational cost decreases by over 30%.
3️⃣ 20% Higher Drilling Efficiency
The optimized crown structure improves rock breaking efficiency, delivering:
- Faster penetration rate
- Stable hammer energy transfer
- Reduced vibration
More meters drilled per shift.
4️⃣ Improved Borehole Quality
The precision button distribution and crown design ensure:
- Better hole straightness
- Reduced deviation
- Consistent diameter retention
This is critical for foundation drilling, geothermal wells, and mining blast holes.
5️⃣ Reduced Labor Intensity
Longer bit life means:
- Fewer tool changes
- Reduced physical workload
- Improved operational safety
