Selecting The Right Impact Wrench

HOW DOES AN IMPACT WRENCH WORK?

There are different types of air tools being used in the construction and automotives industry: Automotive air tools, pneumatic air tools, compressed air tools, compressed air drills and impact air tool. The most handy air tool being used in large constructions and heavy equipment repair is the impact wrench. A little device that provides very strong impact, the impact wrench is a mechanic must-have.

 

Impact wrenches are most commonly used in automotive repair. Be it a regular car, or a heavy equipment, an automotive mechanic usually regards the impact wrench as one of his main tools. It is also being used in product assembly, especially when there is a need for precise torque output. Powered by air, these wrenches make it easy for the handler to tighten bolts without much effort. The energy is stored in a rotating mass and delivered to the output shaft in an instant, producing high and precise torque output.

This tool is sometimes called torque gun, impactor, or rattle gun. There three main parts to the tool: the hammer, and the anvil. The hammer is the one that rotates. Once it does the motor accelerates the rotation. Mechanical energy is stored as the hammer rotates.

When released, the energy is passed on to the output shaft, or the anvil. The energy is released with such speed that it creates a high-torque impact. After the impact, the hammer continues to rotate. The handler only applies a minimum (but constant) force through the motor accelerating the rotation, but very high torque is being delivered because of the energy stored as the hammer continues to rotate.

The sudden burst of energy makes it very easy for the handler to tighten different kinds of bolts with little effort. This is what makes this air tool very handy. Although it is mainly used by automotive technicians, it is also being used at home and in the office. Wherever a bolt needs to be tightened, an impact wrench would be seen.

These wrenches vary, depending on the socket wrench drive size. There are ΒΌ-inch drive tools for smaller bolts and 3.5-inches for larger equipments. Impact wrenches generally work all sizes of sockets though. There are available socket sets in the market. An automotive mechanic will never be seen without one set. He would just have to have a single handle, and then he can just interchange the sockets in his sets, depending on the size of the bolts he would have to tighten or loosen.

There are different brands of impact wrenches available: Snap-On, Dewalt, Craftsman and Ingrsoll-Rand. Prices also vary depending on the model and number of sockets it can interchange. It would be wise to check on reviews of different brands to see what impact wrench would deliver the most precise torque. The energy is not a part of the question anymore, since all impact wrenches use compressed air for energy derivation. This is an air tool worth buying because it is certain it will be put to much use.
