The Sealey Power Speed Ratchet combines the high torque of a traditional hand ratchet with the faster efficiency of an electric power tool, providing working speeds 10-20 times quicker when tightening/loosening fasteners. No-load speed 200rpm saving the time and fatigue of a traditional hand ratchet wrench. The clutch mechanism is designed so that when the maximum torque is reached (1Nm/0.74ft/lb) a tactile vibration indicates to change over to manual mode for continued tightening or loosening of fasteners. Includes a rechargeable lithium-ion battery, full recharge in just 45 minutes and is fully protected from over-charge, over-discharge or overheating. Ultra smooth 60-tooth ratchet action, twist-reverse and quick release with spring-ball socket retention, power button with LED indicator and locking switch. Supplied with AC adaptor, charging base, magnetic socket insert set and storage case. Maximum Torque: 610Nm (Manual) 1Nm (Electric)., Weight: 1790.0 grams, Manufacturer: Sealey
