We manufacture DTH Hammers in different sizes ranging from 3 to 12. 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 hammer like COP and QL are known fort heir reliability and longevity.
