Irvine has hand and power tools available for sale. These are tools commonly needed and used around the house. The idea of using tools is that they reduce manual labour, making it easier to do certain things. They may be either used manually, or be electrically powered (hence the name power tools). Some examples of hand tools include wrenches, screwdrivers, hammers, saws, tape measures and pliers. These are non-powered. Power tools run on a fuel source, such as electric, pneumatic, liquid fuel, hydraulic, and powder-actuated. Examples include chainsaws, drills, sanders, jackhammers, heat gun, thickness planer, trimmer and many more. These are manufactured by a number of companies, one of more of which may be available at Irvine. These usually come with a warranty. Some of the functions that may be done by these tools include drilling, cutting, shaping, sanding, grinding, routing, polishing, painting, and heating. All such tools, which may be used at home or in commercial establishments, should be used carefully with appropriate attention to safety considerations.
