ÜRÜN AÇIKLAMASI

4 inch QL40 Hammer works with bits using the QL40 shank in 105–130 mm holes. It is suitable for water-well drilling, quarry work, anchors and foundation holes where a compact tool is preferred.

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.
