Maximum Diameter Drilling Performance
The Montabert HC170 is a hydraulic drifter developed for large-diameter drilling tasks where productivity and robustness are critical. It is designed to support continuous drilling operations in challenging surface and underground environments, particularly where long hole and production drilling are required.
Engineering Approach
The HC170 is built around a reinforced structure that prioritizes operational stability and resistance to mechanical stress. Manufactured in France using high-quality steel and advanced production methods, the drifter is engineered to maintain consistent performance during heavy-duty drilling cycles. The integrated hydraulic stop protects the tool during operation and contributes to extended service life.
Operational Strengths
- Designed for large-diameter drilling in demanding geological conditions.
- Stable drilling behaviour during long hole and production drilling operations.
- High energy output combined with controlled impact characteristics.
- Durable construction suitable for continuous and intensive work cycles.
- Effective performance in both surface and underground applications.
Typical Applications
- Production drilling in surface quarry and benching operations.
- Anchoring work in construction and mining projects.
- Long hole drilling in underground mining.
- Survey and boring operations in hard rock conditions.
