If you've ever worked with fiber cement material, you know cutting it can be tough on both you and your saw. This SideWinder has a blade guard extension and dust channel to funnel silica dust into the included vacuum hose to be collected by your jobsite vac. Cut siding and trim straight and clean all day with less fatigue, thanks to the lightweight yet rugged magnesium components. And nothing tops SkilSaw's Dual-Field motor for durability. This saw even helps keep the vacuum hose and power cord from getting in your way with its unique no-mar cord sleeve. Big job or small job, this SideWinder will leave all other circular saws in the dust.
