Electric Impact Wrench Basics
Tuesday, September 20, 2011
An electric impact wrench ( http://electricimpactwrench4u.com )is a tool designed to allow mechanics to apply high amounts of torque to a nut and bolt fastening in order to loosen or tighten the fastening with a minimum of effort. Impact wrenches have traditionally required a connection to an air supply in order to generate the necessary power required to apply the necessary force to tighten and loosen nuts properly. One of the latest developments in the market is the release of a high quality cordless impact wrench that does not need to be connected with an air compressor to gain power.
One of the biggest criticisms applied to traditional air guns is that they are quite an unwieldy tool to use - particularly in a restricted environment such as a workshop. An air gun or impact wrench has traditionally required a great deal of air pressure in order to give it the force needed to work properly, and this has meant it being connected permanently to an air supply or compressor, and having a large trailing air hose all the time. With a cordless impact wrench, it is possible to entirely dispense with the air hose and air compressor, and give yourself the freedom to move around the workshop quickly and conveniently.
Some people think that cordless tools lack power, but this is no longer true in absolute terms. It is of course correct that a cordless tool will often offer less power than a tool that is corded or runs from a compressor, but once you realise that the same cordless tool is actually offering more power than a corded tool from ten years ago then this consideration becomes largely irrelevant. If an old corded tool worked adequately, then surely a modern tool of the same power is good enough? The torque required to undo a nut has not changed appreciably after all.
Although the initial outlay for a cordless impact wrench often seems high when compared to traditional models, it is important to bear in mind that without the requirement for a full power air compressor, the total purchase price for the system is much lower, and more affordable to different people, making them accessible to home users. Traditionally, despite offering a full range of tools, different tool manufacturers appeal to a different group of people. Manufacturers like Makita, despite their high levels of build quality and modern reliability are typically seen as being more driven towards the consumer market rather than more recognised toolmakers like DeWalt and Ingersoll Rand, which offer a much better reputation, and are traditionally the first choice for professionals.
Each type of impact wrench provides a variety of different pros and cons that should be considered prior to making the selection. Whether the choice is made to purchase the impact cordless wrench, the air-powered model, or one that is electric powered, the power tool will greatly increase the speed at which work is done, while reducing the users’ effort.
