The history of drilling technology dates back centuries, with early humans using rudimentary tools made of stone and wood. However, the modern construction drilling machine began to take shape in the late 19th century, during the Industrial Revolution. Innovations in steam power and later in electric motors led to the development of more complex drilling machines that could penetrate harder materials with greater efficiency. Over the years, drilling machines have incorporated hydraulic systems, computerized controls, and advanced materials, significantly increasing their capabilities and applications.

The primary function of gear oil is to lubricate the moving parts within the transmission, including gears, bearings, and synchronizers. This lubrication reduces friction, which is essential for maintaining operational efficiency and preventing overheating. Excessive friction can lead to premature wear, reducing the lifespan of the transmission and leading to costly repairs. Moreover, gear oil also acts as a hydraulic fluid that enables the proper functioning of the gears during shifting.
