ÜRÜN AÇIKLAMASI

5 inch QL50 Hammer works with bits using the QL50 shank in 133–152 mm holes. It is suitable for water wells, geothermal work and medium-diameter rock drilling.

Air demand rises as bit diameter and hole depth increase. Pressure losses in the drill string and any water inflow should be included in the compressor calculation.
