We produce an extensive range of DTH Bits using high gradesteel alloy, in various diameters ranging between 65 to 200mm (low air pressure) and 3" to 12" (high air pressure). These are available in different models and styles to suit specific drillingcondition under different level. DTH bits manufactured by us are of long lasting quality to carry out the hole operations efficiently.
These bits provide efficient drilling and absolute balancing wear and fissure resistance. Easily penetrable for water well drilling and blasting holes for mining industry, these are designed to give superb performance.
