The cordless tools are easier to use in the typical tool box which includes a drill and/or drill/drivers, table saw, and reciprocating saw. Small, lightweight, usually handheld, cordless power tools do not need an external power source. Cordless leaf blowers and weed eaters, for example, give you more flexibility in tight spaces or small areas.
Therein lies the practicality of such devices; they can be used anywhere. Such hand-held power tools include a circular saw or trim saw, planer, and jigsaw.
The reason that a cordless drill is so useful is the fact that there are numerous assembly tools, which makes it useful for many repairs. The second reason is that you do not need an extension cord attached to the tool so it can be used anywhere.
Health and safety is of major importance on work sites. Not all jobs can be carried out near to a wall socket, so using corded power tools often means having wires and extension cables trailing around the place, causing a trip hazard to anyone else in the area. Workmen often spend more time putting out warning signs and covering wires in walkways rather than getting on with the job. A cordless tool, however, makes the job much easier and quicker, as well as safer for all concerned.
Purchasing fuel cells can get expensive but improved mobility and compact size justifies the cost for some jobs. They are also a good choice for someone who has an occasional need for a nailer and the huge investment in a compressor doesn't make sense. Cordless nailers make projects like installing moulding and overhead framing easier and quicker. The use of cordless tools increases the labour efficiency. The assembly tools are widely used in mass and large-lot production operations.
