R.s. International Trade Co. Ltd. supplies DTH drill bits with DHD shanks, designed for hole diameters from 85mm to 305mm. The bits feature flat faces with 8 dome and 8 semi-ballistic carbide buttons, optimized for hard and abrasive rock formations. These are manufactured for compatibility with Atlas Copco and Sandvik hammer systems, and are commonly used in water well, mining, and construction drilling.
The bit body is made from high-grade alloy steel with advanced heat treatment to improve fatigue resistance. The carbide buttons are dome-shaped for maximum impact durability in hard rock, or semi-ballistic for medium-hard formations with moderate abrasion. The internal structure follows HD series design principles to maximize energy transfer and reduce air consumption. Surface finish includes shot peening and anti-corrosion coating for extended service life.
These bits are primarily sourced by contractors in mining operations in Southeast Asia and Africa, and for water well projects in arid regions. Trade terms are FOB Qingdao or Shanghai, with lead times of 15 to 25 days. Packaging is in plywood cases with pallet support. Buyers should confirm shank type, button count, and face design against their hammer model before ordering, as compatibility is critical.

Sourcing DTH Drill Bit from R.s. International Trade Co. Ltd. - China Import Guide
Verify the shank type and bit diameter match your hammer system before ordering. Confirm whether the bit is designed for DHD350R, DHD380, or another variant. Check that the button configuration (8 dome + 8 semi-ballistic) aligns with your rock conditions. Request a sample or test report if drilling in abrasive or mixed formations.
Lead time is 15 to 25 days from order confirmation. Shipping is typically FOB Qingdao or Shanghai by sea, with air freight available for urgent orders. Payment terms are commonly 30% advance, 70% against BL copy. Incoterms must be specified in writing. Packaging is in plywood cases with pallets; confirm if export labeling and customs documentation are included.
For quality control, request a hardness test report for the bit body and a button protrusion measurement log. Inspect each bit for button alignment, surface cracks, and weld integrity before use. Retain a sample from each shipment for comparison. Ensure the supplier provides a material certificate for the alloy steel and carbide inserts, even if not mandatory in your region.
