(55mm) thick, on the jobsite or off the guide rail freehand. This is a cordless carpentry saw built for framers, roofers, deck builders, and general contractors who need one saw that handles both rough cutting and repeatable, guide-rail-precise crosscuts without swapping tools. It replaces SKU 576164, the HKC 55 Basic, and this generation brings a real functional upgrade rather than a cosmetic refresh: sensor-based KickbackStop is genuinely new here, added specifically because the previous-generation saw did not have any kickback-arresting technology at all.\u003c\/p\u003e\n\u003cp\u003eKickbackStop reacts in a fraction of a second to arrest the motor and blade if the saw binds or kicks back mid-cut, which cuts down on the disruption — and the risk — that comes with a jammed blade on a jobsite saw. Alongside that new safety system, this saw also picks up a thinner blade: a new 1\/16-in. (1.6mm) thin-kerf blade replaces the 1.8mm blade used on the previous generation, cutting with less resistance for longer runtime and noticeably higher torque, especially when paired with Festool's TBX 8 Tabless Battery. Idle speed is also faster on this model, running at 5,200 RPM versus 4,500 RPM on the saw it replaces — a real increase in cutting speed, not just a spec sheet number. Bevel adjustment runs from 0 to 50 degrees, which is unchanged from the previous generation and already covers the range most framing and sheathing work requires.\u003c\/p\u003e\n\u003cp\u003eBeyond raw cutting power, the HKC 55 K is built to function as a mobile miter saw system when paired with Festool's FSK cross-cutting guide rail, available in 9-3\/4-in, 16-1\/2-in, and 26-3\/8-in cutting lengths. Built-in angle guides from -60 to +60 degrees give you repeatable angled crosscuts, and an automatic return function resets the saw to the start of the cut after each pass — useful when you're crosscutting a stack of deck boards or roof battens to the same length one after another. A conveniently placed guard lever opens the blade guard for a clear view of the cut line while keeping your hand clear of the blade, and a built-in riving knife keeps the blade from binding in the material as you push through a rip cut. Depth of cut adjusts with a spring-supported plunge function, so you can preset a depth and start the cut mid-material rather than only from an edge.\u003c\/p\u003e\n\u003cp\u003eSystem compatibility runs through Festool's 18V battery platform and guide rail ecosystem. The saw is optimized for the TBX 8 Tabless Battery but also runs on the standard 5.0Ah Li-HighPower pack, and it's fully compatible with Festool's straight FS guide rails for rip cuts in addition to the FSK cross-cutting rail. Blade changes use the FastFix spindle lock for quick swaps between standard 160mm blades.\u003c\/p\u003e\n\u003cp\u003eThis saw is built for anyone doing structural or rough carpentry work where speed, portability, and repeatable cuts matter more than fine finish work — framing crews, deck and fence builders, roofers cutting battens and sheathing to size, and general contractors who need a saw that goes from rip-cutting OSB to precise angled crosscuts without switching tools. If your work is mostly finish carpentry on hardwood and sheet goods where a thinner cut and dust extraction matter more than raw rough-cutting speed, Festool's track saw line is the better fit — the HKC 55 K is built for the framing and structural side of the job.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\u003csummary\u003e\u003ch2\u003eA Compact Cordless Carpentry Saw Built for the Jobsite\u003c\/h2\u003e\u003c\/summary\u003e\u003cdiv class=\"acc-body\"\u003e\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"img\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/1582\/5958\/files\/50175543378214_9051b696b02e.jpg\" alt=\"Festool HKC 55 K Cordless Carpentry Saw close-up showing the compact saw body, blade guard, and cutting base for portable wood cutting on the jobsite\" class=\"tnblock-img\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"copy\"\u003e\n\u003cp\u003eA compact body and a conveniently placed guard lever keep the blade in view without putting your hand near it, so lining up on a cut mark or starting a plunge cut mid-sheet stays fast and controlled.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGuard lever opens the blade cover for a clear sightline on the cutline\u003c\/li\u003e\n\u003cli\u003eBuilt-in riving knife prevents the blade from binding during rip cuts\u003c\/li\u003e\n\u003cli\u003eSpring-supported plunge function for cutting depth set from a preset scale\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-benefits-2\" class=\"acc flip\"\u003e\u003csummary\u003e\u003ch2\u003eStraight Cuts With the Full FS Guide Rail Line\u003c\/h2\u003e\u003c\/summary\u003e\u003cdiv class=\"acc-body\"\u003e\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"img\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/1582\/5958\/files\/50175543378214_30dbffff6fa2.jpg\" alt=\"Festool HKC 55 K Cordless Carpentry Saw shown with Festool guide rail systems for repeated cross cuts and straight cuts in wood on a jobsite wall display\" class=\"tnblock-img\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"copy\"\u003e\n\u003cp\u003eStraight, splinter-free rip cuts on long stock come down to how well the saw locks onto its guide rail.
