Operating principle: 1. When drilling starts, the reamer swings out and reams the pilot-hole wide enough for the casing tube to slide down behind the drill bit assembly. 2. When the required depth is reached, rotation is reversed carefully, whereupon the reamer swings in, allowing the drill bit assembly to be pulled up through the casing. 3. Casing tubes that are to be left in the drill hole should be sealed at the bottom of the hoe by means of cement grout or some other sealing agent. 4. Drilling continues to the desired depth in the bedrock using a conventional drilling tools. Our Products Advantage: [1] Appearance: Since the heating process has a complete and stable
process, the appearance of the product can be kept consistent, and
the appearance will not be angular and will not hurt the hand. FAQ: Why choose us?
