The Duratool ROD12 is a heavy-duty hammer drill attachment designed for use with hand drills. It is composed of a steel shaft, a drill bit attachment head, and a secure locking mechanism. The ROD12 is designed for drilling in softer materials such as wood, masonry, and aluminum. It has a maximum diameter of 12 millimeters and can handle a maximum load of 2000 lbs. The locking mechanism securely holds the attachment to the drill chuck so it won't come loose when in operation. The bottle opener feature helps make drilling holes in ceilings, walls, and other hard surfaces easier and more efficient.
