Rockwell's new Compact Circular Saw with a 4½" blade cuts 2X4s in a single pass, and is about 50% lighter than conventional 7¼" circular saws. Plus, the lightweight saw's left-handed blade design provides remarkable cut-line visibility. This compact circular saw can essentially replace a DIYer's or professional's need for a full-size 7-1/4" circular saw. This saw was born to cut wood, especially 2" nominal lumber materials. The Rockwell Compact Circular Saw has a dust extraction port and a 1-1/4" vacuum adapter for dust collection. The saw's 4-1/2" blade has a kerf that is less than half the thickness of larger 7-1/4" circular saw blades. Since this smaller, thinner blade takes much less effort and motor strain to cut through the material, the 5 Amp - 3500 rpm saw can match the performance of full-size circular saws. The saw's maximum cutting depth at 90° is 1-11/16" and the bevel capacity at 45° is 1-1/8".
