Handheld concrete saws use diamond saw blades to cut masonry, stone, and reinforced concrete. Handheld concrete saws are portable so they can be moved around a jobsite. They can also be used for making vertical cuts in walls, demolition work, and cutting through automobile and infrastructure wreckage. Corded concrete saws plug into a wired outlet to provide consistent power and long run time. Battery-powered saws are portable and can be used indoors and outdoors. Gas-powered saws don't require access to a wired power source but create fumes and must be used outdoors.
