Product Description

DTH Hammer


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 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.



DTH Bits 

(1) Made from premium quality nickel-alloy steel 25SiMnCrNi2MoVA for increased durability and wear characteristics, and YK 05 tungsten carbide as same grade as internationally well-known brand 
(2) Apply "hot (thermal) -insertion" processing procedure to insert the buttons as same as internationally well-known brand, 
(4) Entire CNC processing procedure ensure the quality consistency and reliable. 
(5) Grade requirements of heat-treatment guarantee durability, Specific heat treatment standards and special "stress relief" processes ensure consistent performance. 
(6) Designed for maximum performance and hole cleaning ability and high penetration rate.
