The brilliant organization that invented the “Cross-Cutting System” in 1989 continues to produce the very best!  Modeled after the newest generation KSS 50cc Cross-Cutting System, Mafell’s cordless KSS 50 18M bl Cross-Cutting System is revolutionizing jobsites with its balance of power and portability.  Perfectly-sized blades and a unique tilting system help this cordless saw tackle two key thresholds when cutting on a track:  2” material at 0° and Two-by material at a 45°.  Lengthwise the KSS 50 is able to cross-cut a full 16” on its world-class track, with adjustable smart stops allowing for diagonal cuts up to 60° in either direction, plus the track is wide enough for the user’s left thumb to properly hold the track at all times.

The press of a button easily removes the cross-cutting track to acquire Mafell’s K 55 18M bl cordless skill saw – sporting the best weight-to-power ratio in its class and a maximum cutting depth over 2-1/4” (58mm).  Side-by-side scales indicate the cutting depth on or off a track, a red pointer marks the exact cutting line when off the track (even during a bevel cut) and bright LEDs highlight a sizeable work area when the switch trigger is pulled.  The front of the saw features an ergonomic second handle, and the Parallel Guide Fence and Roller Edge Guide accessories can be used on either side of the saw as additional weight support (such as during a bevel cut).

Heavy chop saws and extension cords beware the competitive portability of the KSS 50 18M bl!  Even with its track, this cordless saw weighs only 12.6 pounds, making it a safe and easy joy to use.  The saw maintains excellent cutting depth on the lightweight Mafell Guide Rail System (the rails, connecting pieces and clamps are themselves quite transportable in the Guide Pocket bag accessory).  Mafell’s popular dust bag comes standard to capture an impressive amount of sawdust – even during bevel cuts due to its clever design.  Also included is the handy metal carrying case measuring 31" x 12" x 11" that fits the saw, cross-cutting track, charger and batteries perfectly (even the largest Mafell HD batteries).  Most users are able to move around the jobsite all day with two or three batteries thanks to the convenient 120 V charger and the latest brushless 18 V Lithium-ion technology.  Battery charge can be checked anytime with the press of a button, and the processor monitors and controls all factors such as battery charge and temperature to maximize stamina.

There are two versions of the KSS 50 18M bl to choose from.  The “PURE” version is available for users who already have the compatible Mafell/Metabo Batteries and Charger, whereas the Complete KSS 50 18M bl comes with two Mafell Li-HD 99 watt-hour batteries and the 120 V charger.
