The King Tony America M7 3/8” and 1/2” drive Impact Air Ratchets, Nos. NE-399 and NE-499, have the power of an impact with the accessibility of a ratchet. In less than five seconds the NE-399 and the NE-499 offer 180 ft/lbs and 250 ft/lbs of torque, respectively. They have ergonomic designs with convenient reverse and two-position forward ring control. The impact ratchets are small, and with only a 2-1/2" head height they easily reach cramped and narrow spaces.
