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.
Other considerations when choosing the appropriate tool to use include the power source and the speed specification. Different tools use different power sources such as electricity, battery or fuel and hence the proper tool should be selected depending on the available power source. Different machines operate at different speeds depending on the work they are designed to perform for example a combination hammer has a high speed that delivers a high impact force and is ideal for chiseling or drilling in hard concrete walls.
The Bosch company was at the forefront of power tool technology in those early years. Founded in 1886 Germany by Robert Bosch, the company initially focused on automobile components with integrated electric parts, and was responsible for such developments as the first low-voltage magneto ignition. Before long, companies in other industrialized nations began developing the first electric power tools, and Bosch introduced its first power drill in 1932. Today, Bosch still engineers and manufactures automotive parts, and its power tool division has grown to include nearly every household and assembly tool on the market - including power drills, belt sanders, circular saws, and more. As part of the company's growth, it has acquired other successful power tool manufacturers that started during the same early 20th century era.
In the old days when cabinet makers etc. cut material, they used what was available to them during their day to both make the job easier and more precise.
You may also consider manufacturer. Some craftsmen are loyal to one brand or another and some brands are certainly better than others (this difference usually reflects in pricing). Favoring one manufacture(s) over another can more precisely define and simplify your search. Additionally, just as all craftsmen have a specialty, so do manufacturers. Certain brands build the very best of a certain tool - for example, Milwaukee in known for producing some of the absolute best reciprocating saws, and Bosch for the best jigsaws. The master behind each type of power tool can usually be found with just a bit of research.
