Almost any tool is available now as a cordless or battery operated model; with the improvements in batteries that have been made over the past decade, there is really no need now to use tools with cords that just get in the way and can be dangerous hazards. NiCads and lithiums are the most popular with lithium taking the lead and being the primary battery being manufactured fo most tools now. The main complaint with lithiums is that when they run out of power the just stop with no warning. Some of the manufacturers like DeWalt have started to address this issue by adding battery fuel gauge indicators to give the operator an idea of how the battery is powering down; not all batteries have this feature yet. Some of the companies have made huge strides in how the batteries charge. For example, Makita has a built-in shock absorbing feature and a built-in memory chip in the battery to communicate with the Optimum Charger to allow for a more efficient charge during the charging process to optimize the battery's life by actively controlling the current, voltage, and temperature; the charger has a built-in fan to cool the battery to increase the battery's life. One point to note when using these newer lithium batteries is if they become extremely hot, allow them to cool back down, and watch out that they do not get so hot that they explode.
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.
Drills are found in most department stores and are the most used power tools in the world. These tools are handy and can be used with a wide range of jobs. Because drills are used a lot, you should make sure to check the capacity limitations and accessories needed for the drills.
The last way is to start off with a smaller bundled set. Here this is in relation to power tools that are battery-powered. This first set will usually come with one or preferably two batteries; this way you can buy another if you see that the single battery doesn't last long enough for your projects, so you can have one battery charging while you are using the other one. Also as your needs for more specific tools grow, you can add more tools by buying what are called 'bare tools'. This is when you purchase a tool that does not come with a battery, thereby saving you quite a bit in the cost of that power tool. This is something to be careful of when you compare ads; many times the cost is amazingly cheap considering what you would expect and most of the time that is due to the battery not being included. This is not a bad thing. In fact, this is an excellent thing. This way you can purchase tools that you may not have expected to anticipate that you needed at a more reasonable cost for your power tool box.
S. Duncan Black and Alonzo G. Decker founded the Black & Decker small machine shop in 1910 in Baltimore, Maryland; and the duo found their niche in the power tool industry by inventing the electric drill seven years later. The pistol-grip and trigger style drill became popular and is now a staple on construction sites and in households alike. Realizing the profit potential of power tools, Black & Decker has grown and acquired several other popular power tool brands, including DeWalt, Porter Cable, Delta, and Kwikset.
