Dth Hammer and Bits

6 inch QL60 Hammer

DTH hammer for 152–254 mm holes, compatible with the QL60 shank.

ÜRÜN AÇIKLAMASI

6 inch QL60 Hammer works with bits using the QL60 shank in 152–254 mm holes. It is suitable for large water wells, geothermal drilling, mining and hard-rock sections.

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.
