One of the key applications of the hand-held rock drill is in mining operations, where it is used to extract minerals and ore from underground deposits. Miners rely on this tool to create blast holes or access tunnels in hard rock formations, allowing them to safely and efficiently extract valuable resources. The hand-held rock drill is also commonly used in construction projects to bore holes for anchors, bolts, or posts in concrete or rock structures.

Drill rods, typically made from premium quality steel, are slender, cylindrical bars that connect the drilling machinery to the bit at the bottom of the borehole. They serve as a conduit for transmitting torque, drilling fluid, and the force necessary to advance the drill bit into the ground. The term drill rod steel refers to the specific type of steel used in the manufacturing of these rods, which must possess exceptional mechanical properties.
