The initial step is to create a pilot hole that has only a tiny diameter. Drillers inject drilling fluid onto the drill. This then flows via the pipes. High-pressure jets assist the bit to grind the dirt along the stem of the drill.
After drilling, the fluid will transport the cuttings to the main pit in the drill rig. Drillers can choose from a variety of options dependent on the complexity and big the shot.
The locator and operator will alter the pilot hole to maintain the path of bore. The amount of steering needed and the condition of the soil will affect the pilot hole’s speed. Once it has reached the point of exit, the housing and the bit will be removed and replaced by a reamer.
