Down the hole hammers are the ideal tools for rock drilling in water wells, mining and quarry, consolidation and injection.
The last generation series of hammer dth is formed by valveless pneumatic tools with a unique design that makes it one of the most powerful and universal hammers dth on today’s market, that can work with pressure up to 25 BAR.
On the table, you will find the various models oh dth hammers available with the main technical features.
Hole sizes from 60 to 609 mm.

A Down the Hole Hammer is probably the most important component on the drill rig and the DTH system holds many advantages over the alternatives, for instance:
Rotary Drilling is fine for large diameter holes in softer more friable rocks but less effective in hard rock or where small diameter holes are needed.
Top Hammer (Drifter)drilling system can produce satisfactory results for short hole drilling in hard homogenous rock conditions but would likely experience difficulty in deep holes and in soft ground or with large diameters.
The DTH system is by far the most versatile and can be used very successfully in a wide range of ground conditions from soft,through medium to very hard.
Small or large diameter holes with depth capability are all within the scope of the DTH system, which is recognised for providing clean, truly aligned bore holes at high drilling rates with minimal operating cost.
Some unique features of DTH system:
- Capable of drilling in almost all ground conditions
- Constant energy directly behind the bit provides: speed with less power loss & greater hole accuracy.
- Rigid drill string improves hole alignment
- Air flow volume provides efficient flushing and cleaner holes
- Choice of hole diameters are available with the same Hammer
- Easy to service and mantain
- Large chip drilling provides speed with minimal dust emission
These factors are very important to users operating in the many applications within the drilling industry, which can include:
Blast Hole – Water Well – Oil & Gas – Rock Anchor – Ground Consolidation – Pile – Seismic – Directional and Mineral Exploration Drilling.
Adriatech down the hole Hammers provide customers with these distinct benefits, as well as being able to operate across a wide air pressure range and still continue to provide maximum output with comforting reliability.
Adriatech down the hole Hammers incorporate unique designs, use special steel and undergo closely guarded processes to make them stand out from other makes.
Mincon offer:
- Additional Flushing capability for cleaner holes, particularty at depth
- Case hardened outer components for reduced wear in abrasive rocks
- Heavy Duty options for tougher conditions
- Reversible Wear Sleeves on the larger models for extra life
- Effective Check Valve for drilling in wet holes
- Unique internal mounting concept removes need for shims or special tools
