DTH Hammers(3''-32'')
DTH hammers from Changsha Tianhe Drilling Tools And Machinery Co., Ltd. cover sizes from 3 inches to 32 inches, designed for high-energy impact drilling in hard rock formations. These hammers are built for compatibility with standard drill rigs and operate efficiently at pressures between 1.0 and 3.0 MPa. The hammer bodies are constructed from high-tensile alloy steel with internal components machined to precise tolerances for consistent performance.
The product line includes hammers with single or dual valve systems, optimized for different rock hardness levels. Button bits are typically fitted with tungsten carbide inserts of YG8 or YG11 grade, with diameters matching the hammer size. The design minimizes piston wear and valve fatigue through hardened steel surfaces and optimized airflow channels. These are not low-pressure tools; they are engineered for medium to high-pressure applications in mining and quarrying.
Customers include underground mining operators in South America, tunneling contractors in Southeast Asia, and geological survey teams requiring deep borehole penetration. The supplier ships in steel-reinforced wooden crates, with each hammer individually cushioned. Packaging is designed for ocean freight. MOQ is not specified, but bulk orders are handled. Trade terms are negotiable under FOB or CIF, with delivery times dependent on order volume and production schedule.

| Carbide Insert Grade | YG8 or YG11 (typical for medium to hard rock) |
| Hammer Body Material | 42CrMo4 alloy steel, forged and tempered |
| Typical Piston Hardness | HRC 50 to 54 |
| Airflow Requirement per Inch | Typical: 0.8 to 1.2 m³/min per inch of hammer diameter |
| Standard Shank Type | ANSI/ISO DTH shanks (compatible with 3" to 12" systems) |

Sourcing DTH Hammers(3''-32'') from Changsha Tianhe Drilling Tools And Machinery Co., Ltd. - China Import Guide
Verify the exact hammer size and shank type match your rig’s specifications before ordering. Confirm the carbide insert grade and valve configuration with the supplier, as these affect performance in different rock types. Request a sample hammer for testing under your operational conditions, especially if drilling in abrasive or fractured formations.
Confirm the Incoterms (FOB or CIF) and packaging details. Standard export packaging is steel-reinforced wooden crates with internal cushioning. Ask if desiccants are included to prevent corrosion during long sea voyages. Lead time is not provided and must be negotiated. Payment terms typically require 30% advance, 70% against BL copy. Ensure the supplier provides a material test report and packing list for customs clearance.
Upon receipt, inspect each hammer for surface cracks, burrs, or misaligned valves. Use a pressure gauge to test valve seal integrity at 2.5 MPa. Check shank diameter with a micrometer against the stated tolerance. Retain samples for third-party inspection if required. For large orders, request a batch test report for hammer body hardness and valve performance to ensure consistency.
