Human beings have been using the tools from the ancient period for various purposes. They used axe like tools for hunting the animals and hand drill tools for making ornaments. Therefore, tools have become a part in the human’s life. Industrial revolution has changed the ordinary tools into the power tools which are more efficient than the traditional tools. In our period, the power tools are driven by compressed air, electric power and some other sources which are helpful in increasing the productivity.
Also there are two types of power tools available in the mobility perspective. They are corded power tools and cordless power tools. The cordless power tools are driven by the rechargeable batteries. The efficiency of the cordless power tools are less when compared to that of corded tools. There is another type available which is driven by petrol. But these kinds of tools are used when there is no concern for noise.
