Designed to provide big power in a lightweight, compact package, the SKIL PWR CORE 20™ Brushless 20V 4 ½-Inch Compact Circular Saw is made for working overhead or in hard-to-reach areas. This cordless SKIL saw cuts 2x material in a single pass at 90 degrees and 1x material at 45 degrees, and its integrated dust port directs sawdust away from the work area. At 38 percent lighter than SKIL CR5413, this mini circular saw is easily maneuverable. This cordless circular saw comes with a 24-tooth carbide-tipped blade, rip fence, vacuum adapter, and Allen key. It's compatible with any PWR CORE 20™ battery (available separately), which features industry-leading battery technology that wraps each cell with cooling material to keep the battery powering on for 25% longer runtime and 2X battery life.
