Performance
Accuracy and Precision:
One of the most remarkable features of the Festool Kapex KS 120 REB is its unparalleled accuracy and precision. This is largely due to its innovative dual-laser system, which casts two superimposed laser lines on the workpiece, enabling users to see exactly where their cuts will land.
The saw’s bevel gauge and miter gauge are also highly accurate, making it easy to set precise angles for flawless cuts. In addition to these features, the Kapex KS 120 REB uses a cutting-edge rail system that ensures smooth, straight cuts every time.
This system eliminates any play between the saw’s head and base, so there’s no risk of wobbling or slipping during use. All these features combined make this miter saw an ideal choice for professionals who need high-quality results every time.
Power and Speed:
The Kapex KS 120 REB boasts an impressive 1600 watt motor that delivers enough power to tackle even the toughest jobs with ease. With variable speed control ranging from 1350 rpm up to a maximum of 3550 rpm, this miter saw can handle anything from delicate trimming work to heavy-duty cutting tasks.
Whether you’re working with hardwoods or softwoods, this tool provides reliable performance every time. The motor is also designed with overload protection, ensuring that it doesn’t overheat or stall out during extended use.

Dust Collection:
Another standout feature of the Kapex KS 120 REB is its exceptional dust extraction system. The saw comes equipped with an efficient dust hood that captures up to 91% of all dust generated during use. Users can work with ease, free from the fear of inhaling or having debris enter their sight, due to this feature’s ability to provide a clean atmosphere.
The dust hood can be attached to a vacuum system using the integrated hose port, which creates a powerful suction that pulls dust and debris directly into the vacuum bag. This feature not only ensures a cleaner work environment but also prolongs the life of the saw’s internal components.
Cutting Capacity:
The Festool miter saw 12 inch is designed for precision cutting but has some limitations when it comes to cutting capacity. This miter saw can handle materials up to 30cm (12 inches) wide and 10cm (3-15/16 inches) thick, which is impressive for a saw of its size.
