Down The hole dth hammer Mission DHD QL SD manufacturer

1.Valveless air distribution.More reliable. 2.Simple design of the piston.long life span. 3.More efficient energy transfer,faster drilling speed,lower air consumption and lower oil consumption. 4.Fewer internal parts,simple structure,long life span,less failure and easier to maintain because all the parts are heat hardened. 5.Easy to disassemble because the top sub,the drive chuck and the external cylinder are connected by multiple steps thread.

Products Details

Product overviewDTH 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 254 mm, smaller blast holes are generally drilled using top hammer, and larger holes generally use rotary machines. Our hammer like COP and QL are known for their reliability and longevity.
