    2. When required depth is reached, the dill is reversed and the reamer swings in, allowing the bit to pass through the casing.
    3. Casing tube is pulled out directly or fixed at the bottom of the hole by means of cement grout or other ragglutinant.
    4. Drilling continues to the desired depth using conventional DTH equipment. 3'' PGZ82-3.5-108/6: shank for TND-IR3.5 / DHD3.5 / TD3.5 hammer PGZ90-3.5-114/6: shank for TND-IR3.5 / DHD3.5 / TD3.5 hammer
