This 1/2 inch 45 tooth ratchet is made of high quality Chrome Alloy for durability.        
At 8-degree rotation angle, it not only gets the job done faster, it turns fasteners in tight spaces and increases the range of use of the tool. Precision-machined gears provide smooth ratcheting action and withstand high torque.        
Bi-directional ratcheting gears. Forward/reverse switch moves smoothly, allowing easy direction changes in the middle of a project without removing the socket from the fastener.  Easily removed by pressing the “Push” button on the socket, even allowing one-handed socket changes. Quick release feature makes switching between sockets a breeze.        
This ratchet is great for quick removal and replacement of most threaded fasteners and features a 90 tooth mechanism to ensure a firm grip on nuts and bolts. Excellent quick-release ratchet for any home or professional toolbox.
