The Skil PWR CORE compact cordless circular saw is a lightweight and powerful model that can be operated with one hand. The brushless motor delivers 6000 revolutions per minute. Brushless technology means not only high power, but also a long service life. The saw's blade size is 4-1/2 inches, and despite its compact size, it can easily handle serious tasks. It can cut a 2x4 board at a 90-degree angle in one pass, and when cutting at 45 degrees, it can handle “one board thick” material. It comes with a quality 24-tooth carbide disk. It is ultra-thin, which provides an accurate and clean cut. Built-in dust extraction directs sawdust away from the cutting line, so you can always see clearly where you are cutting - no dust in your eyes or on the marking line.
