The KTC Tools Nepros 1/2” sq. Ratchet Handle, No. NBR490, houses a 90-tooth gear in a compact head to achieve a feed angle of only 4 degrees. Designed to meet requirements for ease of use, it offers smooth action, strength on par with older 36-tooth gear models and a compact size. Providing a light return travel and quiet operation, the tool's union mechanism ensures that the socket will not disconnect from the ratchet unless the button is pushed.
