Are you facing numerous difficulties in rock drilling operations in narrow spaces and complex terrains? Don't worry. The YN27C internal combustion rock drill is here to assist you! It integrates a small gasoline engine, air compressor, and rock drill into one unit, and is simple to operate. Just one person can easily handle it. It has a powerful driving force. When drilling holes in rocks, it can work in both the vertical downward direction and the horizontal upward direction with an angle of less than 45°. The deepest drilling depth can reach up to six meters, and the drilling speed is ≥ 250mm/min, saving both time and effort. Moreover, it has an extremely wide adaptability. Whether it's on a high mountain or on flat ground, in a sweltering area with a temperature of 40°C, or in a frigid region with a temperature as low as minus 40°C, it can operate stably. The main unit weighs only 27 kilograms, making it convenient to carry. It is especially suitable for high mountains, areas without power sources or air pressure equipment, and temporary projects with great mobility. By replacing a few components, it can also be transformed into a crusher or a tamper, achieving multiple functions with one machine! - @jefferyboss11
