Corded and cordless models are both available.
Cordless circular saws let you work virtually anywhere but remember to bring an extra
battery pack or two. They're also smaller than most corded models and work well in tight spaces. Corded circular saws limit your mobility a bit, but they also deliver more power. Different
circular saw blades are available for different applications. This includes high-speed steel blades, carbide-tipped blades, tile-cutting blades, and concrete blades.
