Import Dth Hammers(3''-32'') — Buy in Bulk from Supplier in China

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.
