The Matco 3/8" Heavy Duty Air Ratchet, No. MT 2858, delivers 130 ft./lbs. of "ultimate torque." This power tool includes a patented captured head and patented greaseable yoke with 360-degree rotating side exhaust. The rapid-response variable-speed trigger allows for one-finger operation and unmatched control. Featuring one of the largest motors ever used in a ratchet, the tool is still contained in relatively small housing, for more power in a smaller package.
