Make sure you understand how to use the tools before starting any project. However, if the job is complicated, it is advisable you hire a contractor who can complete the project professionally.
In 1923, American inventor Raymond DeWalt introduced the world's first radial arm saw, a sliding circular saw that could make long cuts with accuracy. One year later, he founded the DeWalt power tool company in Baltimore, Maryland; another company that has grown substantially over the last 85 years. At the forefront of portable power tool technology, DeWalt's power tools are revered by carpenters and homeowners alike for their long-life, durable cordless battery-styled power drill, circular saws, and other power tools; and the company currently manufactures over 200 types of power tools worldwide.
Just recently, I had to have some work performed at my home, and when I looked in the local yellow pages for a craftsman, I was surprised to see independent businesses that from their own admission, not been in business long, offering the same or similar service as the more well known and established businesses. For my own peace of mind I went with an older business, but that may change as time and needs progresses.
Lastly, if you can, it's good to hold the tool before you buy it. Simply being able to feel the tool in your hands to ensure comfort and functionality can be a big indicator of whether the tool is a good fit. Some manufacturers also offer a (around 30 day) Satisfaction Guarantee - this allows you to use the tool once or twice before determining if you're entirely happy with the investment.
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.
