CIR70 Water well drilling mining rock drilling DTH hammer
DTH hammer is used for drilling holes through a wide range of rock types, the variety of which continues to extend well beyond the original conception of early blast hole drilling. Down-the-Hole refers to where the hammer action occurs when compared to drifter hammers, which hammer on top of the drill string. The DTH hammer piston always makes direct contact with the drill bit and there is generally no loss of transmitted energy as the hammer drills deeper, as is the case with drifter (top hammer) rigs. Win Drill offers a wide range of DTH hammers suitable for a variety of drilling operations. Our Down the Hole hammers provide the most versatile and cost effective rock drilling method. It’s widely utilized for foundation work, landslide prevention work, quarrying services, marine civil work, etc.

CIR SERIES CIR50/CIR60/CIR65/CIR70/CIR76/CIR90/CIR110/CIR130/CIR150/CIR170
1. CIR series is steel valve type hammers designed for high performance at low operating air pressure.
The strong energy of single impact and the low engergy consumption in rock crushing.
2. CIR series hammers maximizes energy output and reduce service requirements.
3. A good performance in central air exhaust and cutting discharge, which reduces the repeated crushing of rock.
4. All critical internal components are heat treated under strict control to maximize tool longevity.
EXCLUSIVE FEATURES The patent of steel valve design increases the wok efficiency, it is 20% at least.
