The Precision of This Festool Circular Saw Just Might Make Your Miter Saw Jealous

4 min readLike a lot of Festool products, my preconceived notion of the HKC 55 Cordless Circular Saw was that it was expensive, decidedly pro-grade, and probably more saw than most homeowners would ever need.Then, I tested it, and almost immediately, I realized I’d gotten a couple of things wrong. The HKC 55 is light, precise, and well-engineered, but what really caught me off-guard was what happened when I paired it with Festool’s optional FSK 250 crosscut track. This add-on transformed this circular saw into a portable cutting system with the ability to eliminate a whole lot of trips back and forth to the miter saw.ProsExcellent balance and relatively lightweight designFSK 250 crosscut track makes fast, accurate straight and angled cutsOutstanding dust collection when connected to a shop vacCons6-1/4-inch blade limits bevel cutting capacity Key SpecsModelHKC 55Power18VWeight8 lbSpeed4,500 RPMA Different Kind of Circular SawFirst, the HKC 55 is an exceptionally well-engineered circular saw. It’s beautifully balanced, and both the blade depth and bevel controls are conveniently located at the rear of the saw.Bevel adjustments are quick and intuitive. While the depth adjustment took me a minute to get used to (because it looks different from the way I’m accustomed to seeing it on conventional circular saws), once I got my head around it, it was equally easy to use.Trevor RaabBoth bevel and depth adjustment are conveniently located at the rear of the saw.The Crosscut Track Changes EverythingBut the feature that really changes the personality of this saw is Festool’s FSK 250 crosscut track—an optional add-on that, in my opinion, is indispensable and worth every penny.The saw locks onto the short track to create what essentially feels like a handheld miter saw. Set the angle on the track, position it on your workpiece, and make the cut. The system takes a lot of the measuring, lining up, and—more importantly—the guesswork out of making straight and angled cuts. The saw slides smoothly through the cut and retracts back to its starting point when the cut is finished.Trevor RaabThe optional guide track transforms the HKC 55 into an on-the-spot miter saw.After making a handful of cuts, it got me thinking about all the miles I’ve probably walked between a project and my miter saw over the years. Installing trimwork, for example, typically goes something like this: Measure at the wall, walk to the miter saw, make the cut, walk back, check the fit, repeat. With this saw and add-on, you can bring an impressively accurate cutting station right to the work. There’s real value in the time that saves.That doesn’t mean I’m about to sell my miter saw. Nor does it mean the HKC 55 would be my first choice for every circular saw job. Its 6-1/4-inch blade gives up some cutting capacity to the 7-1/4-inch saws I typically reach for when working with dimensional lumber.You can absolutely frame with this circular saw, but for cutting piles of 2x10s or repeatedly making 45-degree bevel cuts through framing lumber, I’d grab a larger conventional circular saw. The HKC 55 feels much more at home doing precise carpentry, finish work, built-ins, flooring, and renovation work where accuracy and portability matter as much as raw cutting power and capacity.Trevor RaabThe 6-1/4-inch blade is ideal for cutting trim and finished plywood.Its dust collection firmly reinforces that impression. Connected to a shop vac, dust extraction is excellent—something I’d especially appreciate when cutting trim, flooring, or other material inside a house. Circular saws aren’t exactly known for leaving a clean workspace behind, but the HKC 55 does a remarkably good job of controlling the mess.It’s Expensive (But Look What You Get)And then there’s the price.That was probably my biggest misconception going into this test. The HKC 55 initially struck me as wildly expensive compared with the cordless circular saws I’d been testing. But after using it, I realized that wasn’t really an apples-to-apples comparison. I was looking at the HKC 55 as a circular saw when it makes more sense to evaluate it as a complete cutting system. Once you account for the two 5.0-Ah batteries, charger, blades, and Festool’s Systainer storage case, the price gap starts to narrow considerably.Trevor RaabTwo batteries and a charger are included with the HKC 55.Trevor RaabEverything nests neatly into Festool’s hard-plastic “Systainer” case.On that note, calling the Systainer a “case” almost sells it short. Everything has a deliberate place inside it, including the saw, batteries, charger, and accessories. It’s so thoughtfully designed that we ended up shooting an unboxing video simply because of the way the entire system comes together in the Systainer. At the end of the day, you’re not tossing an expensive saw and its accessories into a tool bag and hoping everything is still in one piece tomorrow. You pack the system away properly.Final ThoughtsThat’s really what changed my opinion of the HKC 55. I went into testing it expecting to find a rather complicated, expensive circular saw and realized I’d been looking at it through the wrong lens. Instead, I found a highly specialized cutting system that’s exceptionally good at what it was designed to do.If I’m framing a wall tomorrow, I’m probably still grabbing my 7-1/4-inch circular saw. But if I’m trimming out that wall a little further down the road, the HKC 55 might let me leave the miter saw in the shop.Shop the Festool HKC 55 Cordless Circular SawMore Cordless Circular Saws We RecommendBosch 18V 7-1/4-Inch Cordless Circular SawNow 14% OffSkil Pwrcore 20V Cordless Circular SawDeWalt 20V Max 6-1/2-Inch Cordless Circular SawPaul Russell Smith is a former NYC ironworker turned screenwriter (Grace Point) and home renovation specialist.
