Description

Note: Kapex UG extensions cannot be used in combination with the Kapex crown stops #494369 that attach to the saw. Festool has new crown stops #203356 which are designed for use with the UG extensions.

Key Features

Dialed-In Accuracy

The twin-column guide, dual lasers, and front-mounted fine bevel adjustment make this sliding compound miter saw easier to set precisely and repeat cuts without fighting the setup.

Cleaner Cutting

Festool rates dust extraction at up to 91% when paired with the 36 mm hose and dust hood. That means less cleanup, better cut-line visibility, and less airborne mess indoors.

Portable Full Setup

You get the Kapex saw, UG wheeled stand, and imperial extension wings in one package, so this combo is set up for trim work, repeat cuts, and easier transport right out of the box.

Overview

The Festool 575306-201179 Kapex KS 120 REB Sliding Compound Miter Saw + Imperial Stand w/ Extensions Combo is a premium sliding compound miter saw package built for finish carpentry, trim work, and repeatable precision cuts on the jobsite or in the shop. This is a sliding compound miter saw designed for accurate crosscuts, miters, bevels, and crown work. Model 575306-201179 pairs the Kapex KS 120 REB saw with the UG wheeled stand and imperial support extensions, giving you a complete cutting station instead of just the saw by itself.

What makes this setup matter is how the saw is engineered around precision and speed at the same time. Festool uses a rail-forward design, so the saw head slides on fixed rails rather than needing a lot of clearance behind the machine. In real use, that means you can set the saw closer to a wall or work in tighter hallways and remodel spaces where a traditional rear-rail sliding miter saw eats up valuable room. The twin-column guide with two bearings is there for the same reason: smoother travel, less play, and more confidence when you are trying to hit clean finish cuts instead of rough framing tolerances.

Cut setup is another big part of the Kapex appeal. The dual-line lasers show the kerf clearly, so you can line up cuts from either side without guessing where the blade will land. Festool also gives you a front-mounted rotary bevel control with micro adjustment, an oversized bevel scale, and fine pointers. That is the kind of setup that helps when you are sneaking up on crown, casing, or outside corners where being off a little is still too much. The included MiterFast Angle Transfer Device adds even more value for remodelers and trim guys dealing with walls and corners that are not perfectly square.

On capacity, the product data calls out cutting depths up to 120 mm in the special cutting position and the ability to cut strip material up to 4-5/8 inches vertically against the stop. That gives the Festool Kapex KS 120 REB real 12-inch-class capability in applications where larger stock, tall base, and crown details come into play. The included 60-tooth universal blade supports clean general-purpose finish cuts, and the FastFix blade change system lets you swap blades quickly when the material changes.

Dust collection is one of the reasons people buy into the Kapex system instead of settling for a generic miter saw. Festool states up to 91% dust extraction with the behind-the-cut hood and pivoting 36 mm hose. That matters if you install trim in finished homes, work in occupied spaces, or just want to see your cut line instead of digging through chips. The locking dust port, chip deflector funnel, and extraction-focused hood are all jobsite details that save cleanup time and make indoor work more manageable.

The build is also worth noting. Festool uses a cast magnesium base to keep rigidity up while controlling weight, and the redesigned motor is specifically called out as an upgrade for longer service life. Add the quick-acting brake, overload protection, smooth start-up, front-access controls, cord holder, transport lock, ergonomic grips for left- and right-handed users, and you can see this was designed by people who expect the saw to move from site to site and still hold adjustment.

This combo is especially well suited for finish carpenters, remodelers, cabinet installers, punch-list crews, and serious woodworkers who care more about precision, dust control, and compact setup than just raw saw size. If your work is mostly rough framing, you may not need everything this system brings. But if your day involves miters that need to close cleanly, repeat cuts that need to match, and indoor work where dust matters, this is the kind of saw-and-stand package that earns its keep.

Festool 575306-201179 Kapex KS 120 REB Sliding Compound Miter Saw Precision Without the Usual Footprint

This combo gives you a complete miter saw station that is ready for long material, repeat cuts, and easier jobsite movement. The stand and extension wings are not an afterthought here. They are part of what makes the system practical for finish work.

• Includes the UG wheeled stand and two material support extensions with imperial scales
• Rail-forward saw design helps the setup fit where rear-rail saws can be awkward

Set Angles Faster and Cut Cleaner

The Kapex is built to take guesswork out of finish cuts. Dual lasers show the cut path, and the front bevel controls let you fine-tune angles without reaching around the saw.

• Dual-line lasers mark the material removed by the blade
• Front-mounted micro-adjustable bevel control with large scale and fine pointers

Built for Indoor Work and Finish Carpentry

Some saws are fine outside and a mess inside. This one is clearly aimed at cleaner, more controlled cutting where the finished space matters as much as the cut itself.

• Dust extraction rated up to 91% with the behind-the-cut hood and 36 mm hose
• Quick-acting brake, overload protection, and smooth start-up support controlled operation
