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. These are valve less hammers
with optimized air cycle frequency. These are heavy duty hammers
that well at greater depths demanding less air usage, delivering
minimum performance loss.
We offer IR hammer, DHD3.5, DHD340a, DHD360, DHD380,COP and QL
hammer.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
