Festool 578303 Cordless Carpentry Saw HKC 55 KEB-F-Basic is engineered for power, designed for precision, and built for reliability. From framing to finishing, this cordless circular saw offers the power and flexibility to handle every cut with confidence on any jobsite. Whether making fast cross-cuts with the FSK cross-cutting guide rail, precise straight cuts with the FS guide rail, or accurate angled cuts, the HKC 55 K delivers serious versatility for everyday tasks. The latest generation features KickbackStop technology, a sensor-based mechanism that reacts instantly to stop the motor and blade, reducing disruptions caused by kickback and protecting your workpiece while keeping your workflow smooth. Its newly designed thin-kerf blade with a cutting width of just 1/16” (1.6 mm) provides longer runtime and higher torque, resulting in faster progress, cleaner cuts, and extended battery life. Paired with Festool’s TBX 8 Tabless Battery, this saw delivers maximum performance for demanding jobs, allowing you to cut longer without interruption. The brushless EC-TEC motor combined with advanced electronics ensures top-class cutting strength and efficiency. Effortless handling is made possible through cutting depth adjustment with a plunge feature and a conveniently placed guard lever. Precise bevel cuts from 0° to 50° guarantee repeatable results. Fully compatible with Festool guide rails, this saw integrates seamlessly into your system for precision across a wide range of applications. Ideal for rip and crosscuts in materials up to 2-1/8” (55 mm) thick, the HKC 55 K is perfect for cutting roof battens, profile boards, cladding, decking, and sheet materials like OSB, chipboard, or pressure-resistant wood fiber insulation boards. Battery not included. Model Number: 578303

More power and longer runtime

The brushless EC‑TEC motor delivers maximum power and efficiency.

Mobile miter saw system

Easily connect the HKC 55 K to the FSK cross‑cutting guide rail for precise, angled cross‑cuts. Available cutting lengths of 9-3/4” (250 mm), 16-1/2” (420 mm), or 26-3/8” (670 mm) give you the right capacity for every task.

KickbackStop protection

Sensor‑based KickbackStop reacts in a fraction of a second to stop the motor and blade. This innovation reduces disruptions caused by kickback, helping protect your workpiece and keeping your workflow smooth.

Guard thumb lever

A conveniently placed thumb lever lets you open the guard cover for a clear view of the blade, making operation easier and keeping your hands away from the blade.

Riving knife

The integrated riving knife prevents the blade from binding for unobstructed, stress‑free cutting.

Thin-kerf blade

Specially designed 1/16” (1.6 mm) blades reduce load on the motor, improve runtime, and deliver cleaner cuts. Blade changes are quick and simple with the FastFix spindle stop.

Precise depth control

Push the lever and set the desired cutting depth using the scale. Unlock the plunge position and use the spring‑supported plunge‑cut function for accurate, convenient cuts at preset depths.

Scribe Line = Cut Line

Bevel adjustment from 0° to 50° ensures precise beveled cuts. When used with the guide or cross‑cutting rail, the scribe line is exactly the cut line — even at an angle.

Cut line indicator

Clear view of the scribe line and blade for maximum precision.

Precision guidance

Fully compatible with Festool guide rails, the HKC 55 KS is versatile and excels at crosscuts and rip cuts and pairs well with the FS 1400/2 Guide Rail.

Stay connected

Integrated connectivity with the Festool app gives you detailed information on battery levels, motor temperature, and KickbackStop status, plus access to software updates.
