A Ratchet Handle 1" Drive 660mm Forward and Reverse is a large, heavy-duty tool used for tightening or loosening fasteners, typically in industrial, automotive, or construction applications. 1" Drive refers to the size of the square drive, meaning this ratchet handle is designed to work with 1-inch drive sockets. 660mm is the length of the ratchet handle, providing leverage for high-torque applications, making it easier to turn stubborn fasteners. Forward and Reverse functionality means that the ratchet can rotate in both directions, allowing for tightening (clockwise) and loosening (counterclockwise) of bolts or nuts without having to remove and reposition the tool. This tool is built for tough jobs where significant force is required, offering durability and convenience for heavy-duty tasks.
