Overview

The Festool KS 120 REB Kapex Sliding Compound Miter Saw with Universal & Fine Tooth Kapex Blade Set is a professional sliding compound miter saw package built for finish carpentry, trim installation, and accurate crosscutting on the jobsite or in the shop. This is a sliding compound miter saw designed for precision cutting in trim, molding, sheet goods, and wood framing tasks that demand clean results. Model Number 575306-203150 combines the KS 120 REB Kapex saw with additional Kapex blades so you can get to work with both general-purpose and finer-finish cutting options.

What makes this saw matter is not just raw capacity, but how much control it gives you while chasing tight miters and clean joints. Festool pairs a twin-column guide with dual-line lasers, front-facing controls, and fine bevel adjustment accurate to the millimeter. On real trim work, that means less time creeping up on a cut, less material wasted, and fewer surprises when you bring two pieces together at an inside or outside corner. The included MiterFast Angle Transfer Device backs that up by letting you move tricky site-measured angles straight to the saw more quickly.

The rail-forward design is one of the big reasons contractors buy a Kapex. Traditional sliding miter saws need rear clearance because the rails travel behind the saw. Here, the motor head slides forward on fixed rails, so the footprint stays compact and the saw can sit closer to a wall. If you work in finished homes, hallways, punch-list spaces, or crowded shops, that detail is not small. It directly affects where you can set up and how much room you need to work safely and efficiently.

Festool also built this saw around precision and portability instead of brute size. The cast magnesium base keeps the structure rigid while helping hold weight to about 47.3 lbs for the saw itself, making it easier to move than many saws with comparable cutting performance. The special cutting position gives the KS 120 REB vertical cutting capacity up to 4-3/4" (120 mm), and the saw can cut crown molding in a nested position up to 6-5/8 inches. That gives trim carpenters serious capacity without dragging around a larger, bulkier platform than necessary.
