Since the ancient Egyptians began using a hand-powered lathe centuries ago, man has striven to make arduous building and assembling tasks easier, quicker, and more efficient through power tools. We've come a long way from those sand-covered turning machines, but the end goal is no different from our desert-dwelling ancestors. Today, nearly every home in every industrialized country houses and uses power tools.
One of the most important precautions that should be taken is to make sure that the exposed moving parts of the power tool is covered and safeguarded, including belts, gears, shafts, pulley, sprockets, spindles, drums, flywheels, and chains. The greatest hazard of power tools, however, is electric shock, so make sure the tool is properly grounded before it is powered on. Also, it is dangerous to use power tools in damp or wet locations, as moisture helps electricity flow more easily through the body. This is one of the reasons rubber gloves and footwear are recommended when working outdoors when it is wet or damp.
Term power tool is used for a tool with a motor. Power tools are used for some specific purposes or operations that are not possible to perform manually. It is generally used to reduce the work of operator. Drill, router, electric sander, lathe and saws are some common types of power tools. Power tools may easily perform a complex or difficult task.
Other considerations when choosing the appropriate tool to use include the power source and the speed specification. Different tools use different power sources such as electricity, battery or fuel and hence the proper tool should be selected depending on the available power source. Different machines operate at different speeds depending on the work they are designed to perform for example a combination hammer has a high speed that delivers a high impact force and is ideal for chiseling or drilling in hard concrete walls.
You should first determine the solidity of the type of concrete you will be working on. This will be a guide to the amount of power you require your power tool to give. Another consideration is the nature of work you wish to perform with the power tool, for example if you will be employing the tool for clipping, chipping or drilling work. Hence you may choose to use a dedicated or general type. A good example is a combination demolition hammer which may be used for all the three applications and a dedicated hammer which can be best used for drilling.
