Product Description Classifying by hammers cutting blowing up way: Conventional DTH hammer & Reverse Circulation DTH hammer (RC hammer)Classifying by hammers rated working pressure: Low air pressure DTH hammer,Mid-Low air pressure DTH hammer,High air pressure DTH hammer,Ultrahigh air pressure DTH hammerClassifying by hammers air distribution and structure characteristics:Hammers with valve & Hammers without valve.Outer diameter:1 inch, 2 inch, 3 inch, 4 inch, 5 inch, 5.5 inch, 6 inch, 7 inch, 8 inch, 9 inch, 10 inch, 12 inch , 15 inch, 24 inch, etc.,Classifying by the assorted bit which with or without foot valve:DTH hammers available for assorted bit which with foot valve & without foot valve.? Other spaecial size can be customized by customer's drawing. The optimum range of hole size for blast hole drilling with DTH is 90 mm to 254 mm (3 ?"-10″). Smaller blast holes are generally drilled using tophammer, and larger holes generally use rotary machines.In other applications, like foundation drilling, DTH hammers can be used with single bit in hole sizes up to . 750 mm (30″). With multiple hammer units CD (Cluster drills) drill holes up to 70″ or 1778 mm.As a rule of thumb, the smallest hole diameter a DTH hammer can drill is its nominal size. A 4 inch hammer will drill a 4 inch (102 mm) hole. The limiting factor is the outside diameter of the hammer, because, as hole diameter reduces, airflow is restricted. Maximum hole size for production drilling is the nominal hammer size plus 1 inch, so for a 4 inch hammer the maximum hole size is 5 inch (127-130 mm).Choosing the right hammer is largely determined by hole size and type of rock formation. Ideally, the size of the hammer should match the required hole dimension as closely as possible, leaving just enough space for cuttings to evacuate the hole.

For water well drilling, its upgraded anti-clog air channels prevent mud or sand buildup - a common issue that causes downtime - and maintain stable performance even when drilling depths exceed 200m.We've also prioritized compatibility: this DTH hammer works seamlessly with most standard DTH drill rigs on the market (e.g., Atla s Copco, Sandvi k), making it easy to integrate into your existing workflow. With customizable sizes (3-inch to 6-inch) and permanent stock for common specifications, we ensure fast delivery and personalized technical advice to match your exact project needs. Backed by top-tier manufacturing standards, it balances durability and cost-effectiveness - helping you reduce maintenance time and boost overall drilling productivity.
