Import Dth Hammers - Th79 — Buy in Bulk from Supplier in China

Changsha Tianhe Drilling Tools And Machinery Co., Ltd. supplies the TH79 DTH hammer, a 79 mm outer‑diameter tool designed for demanding drilling projects. The hammer measures 991 mm in overall length and incorporates a 127 mm stroke, delivering strong percussive force. Its back adapter thread conforms to API 2 3/8" REG, ensuring seamless connection to standard drill rods. The unit operates efficiently within a working air‑pressure range of 1.3‑2.5 MPa, suitable for both dry and wet boreholes.

In the DTH market, typical hammer constructions use high‑strength steel grades such as S355, providing impact energies between 20‑50 kJ; the TH79 aligns with this standard performance envelope. Standard dimensions for midsize hammers include outer diameters from 75‑100 mm and rod lengths around 900‑1200 mm, matching the TH79’s specifications. The design includes sealed bearings and corrosion‑resistant coatings to endure harsh drilling environments. Maintenance is simplified by modular wear‑part assemblies that can be replaced on‑site, reducing equipment downtime.
