The brief history just serves to illustrate the development of the drill and close on the heels of the drill were many other corded and cordless power tools. Mains powered devices operate on a variety of voltages 120v in the US and in Europe we operate on two voltages. We have 220-240v powered tools normally used in the home and for the less demanding applications whereas in the construction arena health and safety demands 110v units powered by 220-240v to 110v transformers. Battery powered tools use different battery types and operate at different voltages. The power screwdriver is the least demanding of the electrically operated tools in the power toolbox and may be supplied with as little as 3.6v batteries. The capability of the batteries has increased year by year as we have seen battery technology move gently from 9.6v to 36v such that we now have tools supplied with batteries rated at 12v, 14.4v, 18v, 24v and 36v. Needless to say the 36v tools are much more expensive than the 12v tools. The development in battery technology has been considerably more than just building larger battery packs. The latest batteries are Lithium-ion or Li-Ion batteries which enable more battery power to be delivered and batteries can be quickly recharged.
Tool warranties are often an underrated asset. Having a good warranty with your tool usually means you're buying from a company that entirely trusts their product will satisfy you - this is a good feeling to carry with you on the job. Most industrial manufacturers include a one year warranty on corded power tools, batteries and chargers, and a three year warranty on cordless tools. Of course, this is only standard - some manufactures offer less and some much more. Hitachi includes a ten year warranty on most of their cordless lithium-ion line.
Founded in 1915 in Japan, the Makita Corporation has also staked its reputation on cordless, battery-powered power tools - most notably, the hand-held drill, which Makita introduced in 1978. Nine years later, the company had a full arsenal of cordless, professional-grade power tools for contractors. Today, Makita manufactures over 350 different power tools, both portable and stationary, and the pronounced teal color emblazoned on all of their tools is often mimicked by others trying to capitalize on Makita's reliable name.
The electric drill was regarded by most as the first powered hand tool. The first electric drill was patented in Australia on 20th August 1889 an attributed to Arthur James Arnot. This first drill was primarily intended for heavy industrial use and was invented before most communities were even supplied with electricity. In 1917, Black and Decker introduced and patented the pistol grip and also the trigger switch familiar on most products available today. This was the basis of the modern electric drill and later models were soon shipped in thousands. 1961 saw the first battery powered drill and as technology improves and prices fall we are now in a position where the battery powered drills have taken over from the corded big brother.
Term power tool is used for a tool with a motor. Power tools are used for some specific purposes or operations that are not possible to perform manually. It is generally used to reduce the work of operator. Drill, router, electric sander, lathe and saws are some common types of power tools. Power tools may easily perform a complex or difficult task.
