In addition to price tag, over the top operational expenses, for instance, essentials and accessories should also be taken into consideration. Depending on the brand of power tool, these essentials might be sandpaper, belts, blades, bits and other miscellaneous items. Hence, cost of these add-ons should also be monitored, before finalising upon a power tool. Take note that cost of these accessories; vary from one tool manufacturer to another.
Users should verify the electrical test label at the time of purchasing new one. They should know all applications, limitations and potential hazards of power tools. Power tools must be operated as per the instructions of manufacturer. They should timely inspect tool for loose or broken switches and other problems.
The early 20th century proved to be a hotbed of power tool advancements, and many companies worked hard to develop profit-turning innovations that moved their products off store shelves and into people's homes. While the term power tool traditionally conjures thoughts of electric drills and sanders, machines like the pipe threader and utility pump are also considered power tools. This is the area the Ridgid company focused on when it was founded in Elyria, Ohio, in 1923. Still a leader in the plumbing tool industry, Ridgid now has a power tool division that focuses exclusively on contemporary power tools and has released its own saws, drills, and even air tools.
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.
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.
