From the Manufacturer The PORTER-CABLE® 18V Circular Saw offers a 6-1/2 inch, 18-tooth carbide-tipped PORTER-CABLE® blade allows cutting of two-inch lumber at a 45-degree bevel. The unit's shoe also can bevel up to 50 degrees and provides a clear line of sight for difficult cuts. A depth-of-cut adjustment gauge helps speed cuts in shallow materials, such as plywood, and maximizes the number of cuts per battery charge. The saw features a spindle lock for easier blade changes, and a 4,000 RPM motor with electric brake that stops instantaneously when the trigger switch is released. Batteries and charger are sold separately.
