A rock drill shank adapter, as the name suggests, serves as an adapter between the drill shank, which is the primary working end of the drill, and the drill rig. It is designed to withstand the immense forces exerted during drilling operations, translating the rotary motion from the drill rig into percussive energy that breaks down rocks and other hard materials. The adapter acts as a bridge, enhancing the transfer of power while minimizing wear and tear on both the drill bit and the machinery.
