6'' 8'' 10''12'' DTH Drilling Hammers for Water Well Drilling and Hard Rock Drilling
1.Description:
-Higher Production
In broken and fractured ground conditions,will often out perform the conventional hammer in terms of penetration rates.
-Dry Sample
Even in certain water bearing stratas it is still possible to collect a dry sample because the cuttings(sample)are collected as they are formed through the face of the drill bit.
-Higher Sample Recovery
Because the sample is collected through the face of the drill bit there is no loss of sample when drilling through broken or fractured ground.And since the bit matched to the chuck size ,there is very little bypass of sample and recovery rates of up to 98% are generally achievable.
2.Applications:
DTH hammers are widely used for mine, quarry, road construction for the drilling and blasting work, water well drilling, slope protection, anchoring, etc.
