DRILL DEEPER
BLAST SMARTER
Built for 24/7 production. Zero compromise
on uptime, hole accuracy, or cost-per-meter.
The Real Costs Killing
Your Quarry's Output
Every hour your drill sits idle, your crusher
line stops and your contracts fall behind.
Poor equipment choices cost more than
the price difference.
Hole Deviation Ruining Your Blast?
Rig Downtime Costs $5,000/Day
Burning Through Bits Every 800m?

WHY DTH OUTPERFORMS TOP HAMMER
IN HARD ROCK QUARRYING
| Criteria | DTH (Down-The-Hole) | Top Hammer |
|---|---|---|
| Rock Hardness Range | f=6–20 (all hardness) | f=6–14 (soft to medium only) |
| Hole Straightness | ±0.5% deviation | ±2–3% deviation |
| Drilling Depth | 15–50m without accuracy loss | Degrades beyond 15m |
| Noise Level | Lower — hammer underground | Higher — surface impact noise |
| Energy Efficiency | Energy delivered at bit face | Energy lost through rod string |
| Hole Diameter Range | 50–200mm | 30–115mm |
PROVEN IN THE FIELD. TRUSTED BY QUARRY OPERATORS WORLDWIDE.
From granite quarries in Southeast Asia to limestone mines in the Middle East — Welldone rigs deliver on every bench.
A medium-sized quarry operation replaced their aging top hammer fleet with 3 × KG420T units. Hole straightness improved from ±2.8% to ±0.6%, reducing re-drilling downtime by 34%.
Road construction contractor required precision pre-splitting on sandstone formations. KT5H's integrated compressor eliminated the need for separate air supply — cutting mobilization cost by USD \$18,000 per project.
High-altitude basalt quarry with no grid power access. HB120 electric DTH units powered by on-site generator — compact footprint allowed deployment on 6m-wide benches unreachable by crawler rigs.
