Power tools: powering our hands and also giving speed to our work

Author: smitama | Posted: 27.08.2008 | Views: 26

In earlier days, man used tools which were made of bones or wood. Then came the metallic tools, made of copper and iron. The modern era is of power tools. They are nothing but normal tools, which are being powered by a motor that can be an electric one, or a gasoline based or one based on compressed air. They may be stationary or portable.

The portable power tools are easier to handle, as they can be taken to any small corner or anywhere you want to work. These tools are used in industries, houses as well as at big and small construction sites. Power tools cover every aspect of the utility that one may think of. They can do painting, shaping, brushing, sanding, drilling, cutting, grinding, and so on. In big factories, stationary power tools are used to increase productivity. The need is of bulk work at such sites and during bulk production, hand held tools would not be of much use.

Electric power tools have gained a lot of popularity and importance in the last couple of decades. The electric power tools are powered by electric motors, which either run on the electric supply from a switch board or from a battery. Again electric power tools are of two types, stationary and portable. The stationary electric power tools are those which use cords and are also meant mostly for heavy works. Examples of this kind are electric drills, electric saws, electric grinders, etc.

The stationary type electric power tools have gained much importance in the recent past. They are not as powerful as the stationary type, but they give us the flexibility of reach and they are generally lighter than the stationary ones. These are powered by either rechargeable batteries or normal throw away batteries. Modern high capacity batteries made of Li-ion are also being used to make the tool run for a longer time, without recharging. The examples of this type are hand held drills, hand held saws, and so on.

Though we may still see mechanical tools in use, but the future indeed lies with the power tools that give us

power, speed and ease of work.
