Power tools information


Power tools include a wide range of devices for fabrication, assembly, construction, and repair.  Most power tools are constructed for long service under heavy use.




Power tools are usually motor-driven and designated as electrical, battery-powered, hydraulic, or pneumatic. Here are some examples of pneumatic power tools:


  • Drills
  • Fastening tools
  • Impact tools 
  • Material removal tools
  • Reciprocating saws
  • Torque wrenches

Selection Criteria

Selecting power tools requires an analysis of both product specifications and features. Because power tools may be used for hours at a time, ergonomic products are often recommended.




Portable power tools can be carried to a job and may be hydraulic, pneumatic, electrical (corded), or battery-operated (cordless). Cordless power tools run on 7.2, 9.6, 12, 14.4, 18, 19.6, or 24-volt batteries. Many are lightweight.




A power drill can have a one-speed or variable speed motor, a reversible motor, and be mounted on a powered drill stand. Suppliers of power tools can provide additional information.




  • A comfortable grip
  • Directional exhaust muffler
  • Vacuum-ready dust evacuation
  • Materials such as composites that combine strength with light weight
  • Lubrication-free motor package
  • Vibration-free design
  • Built-in silencers 



Power tools can be designed for specific purposes. For example, a power sander called a rasper is suitable for marine applications because it is designed for fairing hulls and plugs and stripping bottom paint, leaving a smooth surface.Specialty power tools are available.
