Many power tool accidents have been eliminated by going to cordless power tools. If you operate any type of power tool that has a cord, make sure you have it properly secured. Don t leave the cord out in the open where you or someone else can trip on it. There is the risk of electrocution so make sure the cords aren t frayed. Most power tools are reasonably priced but you are going to run across some heavy duty, top of the line power tools that have a price tag to reflect it. Keep in mind the cost is more than just the purchase price. Take the cost of essentials into consideration as well. Depending on the type of power tool, these essentials can be sandpaper, belts, blades, bits, or a number of other items. The company began in 1917, only making drills. The concept was designed by Duncan Black and Alonzo Decker. By 1928, Black & Decker was beginning to introduce power tools after they took over a small company called Van Dorn Electric Tools. They began making improvements to that line of power tools to come up with the quality power tools we have come to trust today. The on/off switch being in a location that isn t convenient or easy to get to in the event of an emergency is the most common complaint. With saws, the most common complaint for left handed people is that the blade is on the right hand side which makes it difficult for them to operate. The left handed individual has two choices hold it the wrong way and hope the cut ends up being straight or face it the other way around with the blade coming at you and the materials coming at you. Make sure you choose one that has a high level of power and comes with the on/off location in an easy to reach location in the event you need to turn it off in a hurry. 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. Some sanders offer a warning light that tells you when you are using too much pressure. A belt sander, just as the name implies, uses a belt to remove the materials. The handles are designed to help you manipulate the power tool without too much pressure on your part. Disc sanders are commonly used for grinding.
