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.
With technological advancements in industrial equipment, power equipment are now stuffed with plethora of modern features that work wonders, in dimidiating your work. However, do not get carried away by the list of un-ending features. There is a possibility that you might not even use a dime of them. Therefore, figure out your usage first and, then search, compare and filter out the one that fits your bill.
After reviewing government injury and death statistics, accident case reports and newspaper accounts, Forbes.com reported that the most dangerous are those that include blades, such as circular saws, table saws, chainsaws, riding lawn mowers, wood chippers. However, tools that drill or puncture were also reported to be extremely dangerous. Individuals using these tools should make sure that the tools are equipped with automatic shutoff features and guards. With all power tools, however, it is important to identify ways to prevent injury through the proper use of tools and the appropriate use of protective equipment.
One way is to keep an eye out for sales at hardware, big box, or specialty stores. Sometimes the store brands will give you sufficient quality for what you need. Most times you may have to wait a while until these stores put the items that you are looking for on sale. If you do a little research, you may see a trend where certain tools go on sale at specific times during the year. Some of these may be associated with certain holidays like Father's Day, Memorial Day weekend (in the U.S. this is because many folks start their outdoor projects then) and the Chanukah-Christmas season. Just keep checking out fliers and ads for your special tools in the mail & newspapers and on the Internet.
Determine whether you are in the market for a tool kit or if you need only one single tool. Often you may find kits available that include the most frequently used power tools like a drill, impact driver, and reciprocating saw. This is obviously a more expensive investment that buying a drill alone, but if you need these other power tools, its certainly more economical to buy them in a kit than to buy them all separately. This is also helpful if you prefer cordless tools - buying multiple cordless tools from the same manufacturer means you can usually swap a battery between different and multiple tools.
