The Festool Sliding Compound Miter Saw KAPEX KS 120 REB, Model Number 575306, is a precision sliding compound miter saw built for finish carpentry, trim work, and clean crosscuts on the jobsite or in the shop. This is a sliding compound miter saw designed for precise angle cutting in trim, molding, and general carpentry work. If your work depends on repeatable miters, accurate bevels, and cleaner cuts inside finished spaces, this is the kind of saw you buy because it solves real jobsite problems, not because it simply checks a spec sheet.

The big selling point here is accuracy. Festool uses a rail-forward design that keeps the footprint compact while helping prevent head play. In practical terms, that means you do not need the same rear clearance many sliding miter saws require, and you get a saw that stays more controlled through the cut. The dual lasers make setup faster from either side by clearly defining the material being removed, which is especially useful when you are dialing in visible finish cuts where a pencil line and a guess are not good enough.

The saw is also built to make fine adjustments easier instead of turning them into a fight. A micro-adjustable bevel angle with an up-front rotary knob, plus a large bevel scale and fine pointers, gives you better control when you are sneaking up on an exact fit. The variable no-load speed range of 1,400 to 3,600 RPM gives you flexibility across different trim and finish materials, and the 10-1/4 inch blade size is paired with serious cut capacity for molding and specialty cuts.

Dust collection is one of the reasons this saw stands out in real-world use. Festool rates the system for dust extraction up to 91% when paired with the behind-the-cut dust hood and pivoting 36 mm hose. That matters if you are working in a finished home, in a small shop, or on an install where cleanup time cuts into profit. Cleaner cuts are one benefit, but cleaner air and less mess around the saw are what contractors remember after a long day.

For capacity, the numbers are solid and job-relevant. The Festool KAPEX KS 120 REB handles crown molding diagonal cuts up to 6-5/8 inches at both 45 degrees/90 degrees and 90 degrees/90 degrees. Special cutting depth at 90 degrees/90 degrees is 2-1/4 inches by 4-3/4 inches, with additional left and right special cut capacities for bevel work. Miters go 50 degrees to one side and 60 degrees to the other, and bevel range is 47 degrees left and right, which covers the angle work most trim and finish carpenters deal with every week.

From a design standpoint, this is a portable corded saw that balances compact size with pro-level build quality. It runs on 120 VAC power, uses 1,600 watts, includes a 3.5 m cord, and weighs 50.93 lbs according to Festool technical data. That weight puts it in the serious-tool category, but still makes it manageable enough for transport to job sites where a full station setup is worth it. The FastFix blade change system, called out in supplementary product data, is also a practical advantage because it mechanically locks the arbor and trigger for easier one-handed blade changes.

What you are really buying is control. The angle transfer device and hold-down clamp included with the saw back that up, because this tool is clearly aimed at users who care about exact fit, repeatability, and time saved during setup. This is not overkill for a finish carpenter, cabinet installer, remodeler, or serious woodworker. It is the right saw for someone who makes visible cuts, works in customer spaces, and wants dust collection and precision to be part of the system instead of an afterthought.

If you mainly rough-cut framing lumber and do not need fine miter accuracy, there are cheaper saws that will get by. But if your day involves casing, base, crown, interior finish work, built-ins, or precise crosscuts where bad cuts cost money, the Festool Sliding Compound Miter Saw KAPEX KS 120 REB earns its place fast.
