Electric Tools Provide Fast Motorized Muscle
Electric tools generate much more power than a lone human can provide. These tools add the power of electric motors to manual tools. The resulting electric power tools are excellent labor saving devices. The tedious cranking of the hand auger has been replaced by the quick efficiency of the electric drill. The back-breaking hand saw has been outpaced by the fast and easy electric circular saw. Electric sanders smooth woodworking projects thousands of times faster than hand sanding ever could.
Many electric tools operate using standard house current and voltage. This is a great advantage at the worksite, where that is the only type of electrical connection available. Often this means that extension cords must run from the connection to the power tool. This can be a safety hazard at a worksite. First, some extension cords are not rated to handle the currents needed by some power tools. The second danger is that these long cords are a tripping hazard, especially if multiple cords are used.
Battery powered electric tools eliminate the need for extension cords. These power tools utilize small but powerful rechargeable electric batteries. The worker has much more freedom to take his electric tool where it is needed. However, batteries need recharging, and heavy use means more frequent recharging periods. Because recharging may take several hours or overnight, start the job with several fully charged batteries at the beginning of the day. Let all the electric tool batteries recharge each night.
In a workshop, cords and batteries are not problems. All electric tools would simply plug into the house receptacles. Some power tools such as nailers run on compressed air. However, even a nailer needs an electric compressor. Table saws, band saws, sanders, planers, joiners, and even lathes can run on standard electric current. If an electric tool needs more demanding electric power, this can be installed for a nominal fee.
Electric powered tools are superior to tools that run on gasoline, except where electricity is unavailable. For example, loggers in mountainous terrain would certain use gasoline chain saws. For most other jobs, the electrically powered tool has the convenience advantage. On everyday worksites, the work crew using electric tools never has to worry about running out for another can of electricity!
