While you can easily recharge the batteries, some power tools have a battery that gets weaker over time. This means it won t hold much of a charge. You can choose to purchase a replacement battery at that point. There is less of a risk of accidents with a cordless power tool because you don t have to worry about trips and falls due to the cords. Some people just don t feel comfortable operating power tools. That is fine, and you shouldn t feel forced into doing so. This is just opening the door for potential accidents to happen. If you are willing to learn to operate specific power tools that is one thing, but if you feeling pressured to do so you are going to have too much anxiety to operate it. According to OSHA, a large portion of power tool injuries occur because the power source is not removed while changing parts on the power tool. It doesn t matter how much experience you have with the power tool or how quickly you can change the part. Drill bits and saw blades are the most common culprits. Heavy duty work gloves are good to have if you are working with any sharp objects including sheet metal. A full face shield will protect even more when you are using certain power tools. The proper clothing is very important too. It is a good idea to wear long sleeves to prevent burns and cuts, but make sure that the clothing isn t too loose. A mitre saw is a type of circular saw that works well for crosscutting. It is used to cut at exact angles, dimensions, and lengths. For very detailed work, a scroll saw works great. These are both very common tools used in woodworking. A saber saw works well to cut paneling and other thin, flexible materials. Most anything that is build with wood involves using some type of saw. It can be to cut the beams or to cut corners and holes in the middle of the wood without touching the edges. Saws are also one of the most dangerous power tools out there because of the sharp blades and the shear power they have. Saws are also used to cut down limbs and firewood.
