ÜRÜN AÇIKLAMASI

8 inch DHD380 Hammer works with bits using the DHD380 shank in 203–305 mm holes. It is suitable for large water wells, geothermal, mining and infrastructure drilling with high air demand.

The compressor should be selected for both hammer demand and the air velocity needed to lift cuttings. Bit diameter, hole depth and formation conditions should be assessed together.
