The optimum range of hole size for blast drilling with DTH is 90mm to 254mm,smaller blast holes are generally drilled using top hammer, and larger holes generally use rotary machines. Our hammers like COP and QL are known for their reliability and longevity.
These hammers are made corresponding to Drilling Bits to carry out prevalent objectives.
These hammers are used in various down the hole operations like bench Drilling.
They are valve less hammers with optimized air cycle frequency. We also have hammers with valve.
We have heavy duty hammers well at greater depths demanding less air usage, delivering minimum performance loss.
