Determine your preference between cordless and corded power. It's best to understand the limitations and benefits of both types before making this distinction - corded power ensures a constant power source and eliminates hassling with chargers and batteries, it also tends to be more powerful and lightweight. They are, however, tethered to a wall which means limited mobility, use, and strained power with the use of extension cords. Cordless tools, on the other hand, can go anywhere you can go, and with always improving battery technology, they are a powerful, reliable source of portable power with no hassle of a dangling cord.
Unplug the tool before changing bits, accessories or attachments. Remember to check what is behind something for possible electrical wiring or pipes in your path. If you see wires, then you should disconnect them and the power source. Avoid water pipes and always hold the tool by the insulated grasping surfaces.
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.
If you are a serious home user or contractor, go with a good brand name such as Milwaukee, Dewalt, Bosch, Porter Cable or Makita. These manufactures pride themselves on making the best tool. They are constantly putting money into their research and development process to make these tools even better. These professional power tools cost more, but they are made with better technology and materials. They also have a better design that causes less fatigue on the user. Not to mention that these tools are made to last a life time.
Handheld power tools can make work so much easier in industries. They are convenient since one can walk around holding them and be able to do their work uninterrupted. This is why one should also be careful as this can also pose a huge danger to the user. However, these tools are not merely an insular solution to the user as it is also a way to increase effectiveness in more ways than one.
