1/2" DR Reversible Ratchet Pear Head Ratchets are used with sockets. The ratchet, along with the socket attached to it, is the maximum leverage that allows you to apply torque. The reversible mechanism allows the socket to rotate both ways, to tighten and to loosen. The design and dimensions on 1/2" ratchets are ideal for doing assembly and maintenance work on electronic, pneumatic-electric, and electricity-controlled equipment. The maximum recommended torque for 1/2" ratchets is 4500 in-lb. There are two attachment systems for sockets and accessories; the traditional spring-loaded ball detent system, and the QUICK RELEASE system that allows you to attach and detach sockets and accessories to the ratchet. It is ideal for situations where sockets and accessories get slippery on contact with grease and oil, making it difficult to detach them from the ratchet?s drive. With QUICK RELEASE you only need to press the button located on the back side of the ratchet?s head and gravity will pull the socket or accessory off.
