The Matco Tools 16V Cordless Infinium 1/4" Sealed Head Ratchet Kit, No. MCL1638SRKP, is a battery-powered ratchet that features a sealed head design to prevent torque loss and increase tool durability. Its 1/4" drive generates 42 ft-lbs of maximum torque for tough fasteners. A one hand forward and reverse selector at the bottom of the tool head makes direction changes easier in tight spaces. The ratchet offers 300 rpm and features a variable speed enclosed paddly style trigger for increased control. High power trigger-activated LEDs light up large areas and the durable aluminum and glass-filled nylon housing constructions makes the tool more durable.
