ROCKWELL new compact circular saw with a 4-1/2 in blade cuts 2X4s in a single pass and is about 50% lighter than conventional 7-1/4 in circular saws. Plus, the lightweight compact circular saw’s left-handed blade design provides remarkable cut-line visibility. This compact circular saw weighs only 5 lb, so it is easier to transport and maneuver (especially overhead) than many other compact circular saws. The slim, inline grip design provides great comfort, balance and control.
