DTH165-H is the hydraulic-drive option in this quarry-drilling group. Its Ø90–165 mm hole range is larger than the DTH90 entries, and both rotary and feed functions are hydraulic.
Key figures for DTH165-H
| Hole diameter | Ø90–165 mm |
|---|---|
| Maximum drilling depth | 30 m |
| Feed rate | 6–8 / 2–4 m/h as recorded in the source table |
| Stroke | 1.5 m |
| Compressed-air demand | 7–12 m³/min at 0.5–0.7 MPa |
| Rotary / feed source | Hydraulic / hydraulic |
| Equipped drill rod | Ø76 × 1500 mm |
Use the larger hole range as the starting point
The main reason to consider this model is the Ø90–165 mm range. Establish the required hole and compatible hammer/bit combination first, then check whether the listed 30 m maximum depth and 1.5 m stroke fit the drilling plan. The two feed-rate ranges in the old table are not explained; the applicable condition should be clarified in the technical offer.
Quarry layout and services
The drill retains the family's multiple fastening positions, adjustable head connection and quick rod release. For a hydraulic configuration, the quotation should show the complete hydraulic power and hose scope. Compressed-air flow must also be available at the hole, because the DTH hammer and flushing system still depend on it.
