Good quality power tools are essential for craftsmen, tradespeople, and
do-it-yourselfers. Power tool manufacturers generally offer both
higher priced, professional grade tools and lower priced, light duty tools.
In many cases, an expensive, pro quality power tool is appropriate for a
tradesman who uses the tool day in and day out, while an inexpensive tool
may be well suited for a homeowner who uses the tool only occasionally.
Most power tools used in the USA are powered by 120 volt AC current.
However, as NiCad and Lithium Ion batteries have improved in recent years,
cordless tools have become popular. These tools offer greater
flexibility and freedom of movement for home improvement and construction
sites where AC power may not be available.
The primary types of power tools include drills, saws, shaping tools,
and impact tools. Drills are designed to make round holes by means
of a revolving cutting bit. Saws are used to cut solid materials
into specified shapes or lengths. Lathes are
stationary tools that remove unwanted material from a workpiece by
means of a turning operation. Sanders are meant for smoothing rough
surfaces. Impact drivers, hammers, and wrenches typically use a
powered cam and gear mechanism, and are designed to replace traditional
screwdrivers, hammers, and wrenches for many usages.
Some power tools are quite versatile; others are very specialized.
For instance, portable circular saws are used for a wide range of sawing
applications, whereas scroll saws are used specifically to cut intricate
shapes in thin pieces of wood. With such a diverse selection of
power tools available, it is important to understand their intended uses
in order to fully benefit from their many capabilities.
