The Festool HKC 55 KEB-F-Basic (578303) is an 18V cordless circular carpentry saw designed to deliver high torque, accuracy, and efficiency across jobsite framing, timber construction, decking, and finishing work. Powered by a brushless EC-TEC motor and advanced electronics, this saw is optimized for 18V battery operation—particularly with Festool's TBX 8 Tabless Battery or 5.0 Ah Li-HighPower pack—to maximize cutting power and runtime per charge. Supplied as a bare tool inside a Systainer SYS3 M 337 storage case, the HKC 55 KEB-F-Basic handles rip cuts, cross-cuts, and compound angle cuts in solid wood, OSB, chipboard, and profile boards up to 2-1/8 in. (55 mm) thick.

Operational safety and material protection are led by sensor-based KickbackStop technology, which detects binding and stops the motor and blade in a fraction of a second. An integrated riving knife helps prevent material pinch during continuous rip cuts, while a built-in thumb lever lets the operator safely retract the pendulum guard for a clear view of the blade during plunge cuts. The saw features a spring-supported plunge mechanism with an easy-to-read depth scale, FastFix spindle stop for quick blade changes, and an articulating 360-degree dust extraction port compatible with Festool dust extractors or the optional SB/2-TSC/HKC dust bag.

Designed for seamless jobsite versatility, the HKC 55 KEB-F-Basic integrates directly with Festool FSK cross-cutting guide rails (available in 250 mm, 420 mm, and 670 mm cutting lengths) to function as a mobile miter saw system with integrated angle stops from -60 degrees to +60 degrees and an automatic return feature. It is also fully compatible with standard Festool FS guide rails for long, dead-straight rip cuts. When beveling from 0 degrees to 50 degrees, the saw maintains alignment so the scribe line always matches the actual cut line.

Features & Benefits

• Brushless EC-TEC Motor: Delivers long motor service life, high cutting torque, and efficient battery performance under heavy cutting loads.
• Sensor-Based KickbackStop: Detects binding instantly to stop blade rotation, reducing jobsite disruptions and protecting the workpiece and operator.
• 1/16 In. Thin-Kerf Blade System: Specially designed 1.6 mm thin-kerf saw blades reduce motor load to increase cutting speed and extend battery runtime.
• FSK Cross-Cutting Rail Integration: Connects to FSK guide rails to create a portable miter saw system with repeatable angle stops from -60 degrees to +60 degrees and automatic return.
• FS Guide Rail Compatibility: Mounts on standard Festool FS guide rails for precise, splinter-free rip and panel cuts.
• 0° to 50° Bevel Adjustment: Precise angle setting ensures consistent beveling, with the scribe line matching the cut line at any angle setting.
• Spring-Supported Plunge Function: Depth adjustment lever and scale enable accurate preset plunge cuts and controlled entry into sheet goods.
• Guard Thumb Lever: Conveniently located lever allows safe manual retraction of the lower guard for unobstructed view during cut alignment.
• Integrated Riving Knife: Keeps the kerf open to prevent blade pinching and stress-free cutting in solid timber.
• FastFix Spindle Stop: Lockable arbor mechanism makes saw blade changes fast and simple using the onboard hex key.
