The RK437 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. This saw weighs only 5 lbs, so it is easy to transport and maneuver (especially overhead). The slim, inline grip design provides great comfort, balance, and control. The 4 " blade cuts 2X4's in a single pass and is about 50% lighter than conventional 7 " circular saws. Plus, the lightweight saw's left-sided blade design provides remarkable cut-line visibility. 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 6.5 Amp - 4200 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 capactiy at 45 is 1-1/8". The saw also features a dust extraction port and a 1-1/4" vacuum adapter for dust collection and a clean work environment.; 4200 rpm no-load speed provides smoother cutting; 1 3/4? (46mm) cutting capacity with a compact design; Laser guide for ultimate accuracy every time, Cut up to a 45 Bevel; Quick and easy depth adjustment; High efficiency wood blade for 40% faster cutting; Designed for ea.sy one-handed operation; Spindle lock button for easy blade change; Dust extraction facility with build-in dust port; High Intensity Motor provides 15% more power and 20% slimmer body (compared to RK3441k), plus the addition of a laser guide.; Power: 800W; No-load Speed: 4200 rpm; Blade Size: 4 ? ? arbor 3/8?; Bevel Capacity: 0 - 45 ; Machine Weight: 4.4 LBS
