The Mafell KSS 300 cross-cutting system offers finish carpenters, floor-layers and cabinet makers a whole new way to make fast and highly accurate straight and plunge cuts.  This lightweight and innovative circular saw is connected to a unique aluminum guide track composed of a friction pad on the bottom side of the guide and an adjustable "smart" stop for either perfectly square cuts or precise miter cuts up to a 60° angle.  The carpenter simply places the guide track up against the leading edge of the stock and pushes the saw through the wood, without needing to guide the saw or follow the line by eye.  Since the hard plastic edge of the aluminum guide is aligned with the carbide blade, splintering of the top surface of the wood is prevented, even with angle cuts.

The KSS 300 cross-cutting enables you to saw with angular precision and only one hand on the machine.  Its handling is unbeatable!  Thanks to magnesium die-cast components, the entire system weighs only 6.6 lbs.  The FLIPPKEIL riving knife automatically withdraws into the body of the saw during plunge cuts and then returns to its safety position as you advance forward with your cut.  Once the cut has been executed, the saw effortlessly returns to the starting position on the aluminum track via an integrated polyethylene cable.

Since this saw can cut up to 1-1/16" deep at a 45° angle, so it is perfect for window, door, rake and eave trim.  For accurate long cuts, attach this fine saw to the 4.5 foot long Flexi-Guide FX140 and run the saw down the track for a perfectly straight cut.  When your project is complete, the Flexi-Guide can be rolled up and stored with the saw and aluminum guide track in the carrying case.

Stop carrying those heavy tools to your worksite!  The KSS 300 takes the place of a chop saw and table saw, enabling the finish carpenter to make accurate and clean cuts at the work location, rather than walking back and forth to stationary saws.  Within moments of using a KSS 300, you will be convinced that this is one of the most clever inventions of the 21st century -- an ideal tool for shadow gaps, rip, bevel, plunge and angled cuts, as well as free-hand work since the saw can be quickly removed from the aluminum track.
