Import Dth Hammer And Bit — Buy in Bulk from Supplier in China

The DTH hammer and bit from Winner Industry Corp., Ltd is a down-the-hole percussion tool designed for drilling in hard rock formations, commonly used in mining and civil engineering. The tool operates with compressed air to deliver high-frequency impacts directly at the drill face, improving penetration rates in abrasive geologies. Based on the listing, the hammer and bit are constructed from alloy steel with hardened cutting edges, though exact composition and hardness values are not specified. The product is available in multiple sizes to suit varying drill rig capacities and borehole diameters.

Typical industry standards for DTH hammers include operating pressures between 0.7 and 2.1 MPa and bit diameters ranging from 76 mm to 254 mm. The bit shank follows ANSI or ISO 1401 standards for compatibility with standard drill rods. The hammer body is typically forged from chrome-molybdenum steel to resist shock fatigue, while the bit face uses tungsten carbide inserts with a standard hardness of 85-92 HRA. These are typical specifications for industrial-grade DTH tools, not guaranteed values from this supplier.

This tool is primarily purchased by contractors in quarrying, tunneling, and water well drilling operations who require consistent performance in fractured or igneous rock. Buyers commonly require compatibility with Atlas Copco, Sandvik, or Ingersoll Rand rigs. Packaging is typically in steel crates with internal foam padding to prevent damage during transit. Trade terms mentioned include FOB and CIF, but exact MOQ and lead times are not provided. Buyers should confirm these directly with the supplier before ordering.
