Exceptional power and downward cutting motion make this handheld cut-off machine ideal for heavy-duty concrete and metal cutting applications. With a powerful 15-amp, 4.8 maximum horsepower, 4,600-RPM Milwaukee-built motor, this handheld can handle the most extreme jobsite applications. A durable 20-amp overload protection switch prevents premature failure by tripping the tool, not a remote panel breaker, to minimize downtime. A full 4-7/16 in cut depth and downward cutting rotation - usually found just on gas-powered demolition saws -reduces the chance of jamming or kickback. Your line of sight remains clear of dust, debris and sparks. An optimal-angle main grip; oversized, non-slip, wraparound side handle; and durable steel shoe assembly provide enhanced comfort, control and stability. The 2-finger, 1-step trigger requires minimal pressure to engage. Blade, cut-depth and guard angle adjustments are fast and easy because of the spindle lock and large footplate wing nuts. Changes require just a single 5/16 in hex key, unlike the multiple wrench system on competitive products.
