A power tool can be defined as anything that uses a manual or automatic action to accomplish a task. These actions include drilling, sawing, trimming, drilling again, pushing and pulling and the like.

Power tools usually have a motor, a drive system and a clutch. There are some other components to a power tool that is often considered when purchasing one. One of these is the power control unit. This unit controls and regulates the amount of electricity that passes through the battery pack of the tool.

Today, there are various sizes of power tools that are available in the market. Some of them are very large; others small enough to fit in a handbag. You can also purchase power tools in bulk, if you want to save your time in working on each tool separately.
