Festool Kapex KS 120 REB Sliding Compound Miter SawProfessional

The Kapex KS 120 is Festool's premium trim saw, built around precise angle scales, excellent dust extraction, and a compact 47-pound body that trim carpenters love. It's the accuracy-and-dust benchmark when it's working right. The serious caveat is a well-documented history of motor failures, so buyers weigh that against the price.

• Owners and pros widely praise the cut quality and rigidity, with precision to a fraction of a degree
• The far-from-axis miter and bevel scales let you read and set fine angles very accurately
• Dust extraction is best-in-class, capturing around 90 percent with the rear hood and a 36-millimeter hose
• The hold-down clamp, counter-balanced bevel control, and dual lasers are singled out by owners, and at 47 pounds it's compact for a premium saw

• Motor reliability is the dominant complaint, with documented armature and brush failures, and out-of-warranty repair reportedly running well into the hundreds
• Despite the price, some owners struggle to dial in a square cut, with one thread calling it hard to true and another owner spending hours chasing square
• The price is very high for the capacity, since it's a 10-inch blade with a smaller crosscut than 12-inch competitors
• Repair turnaround and parts cost come up often

It takes 260-millimeter fine-tooth blades. The UG Kapex stand with extension wings and crown stops is the common setup, and it integrates with Festool MFT tables and CT extractors on 27 or 36-millimeter hoses. Brushes and the armature are replaceable service parts, which owners end up needing.
