With twice the speed of a conventional rachet, the Groz Dual Drive Ratchet Handle functions both as a conventional ratchet and a twist action ratchet. The Twist action tightens and removes fasteners without moving the handle in tight spaces. In this mode, the drive turns in a fixed direction, regardless of the direction the handle is rotated. The easy-to-use switch mechanism enables the user to switch the mechanism to change direction. The 52 Teeth Gear design provides optimum torque while the Quick Release Push button immediately releases the socket.
