Whether it's on the roof or on a level floor, whether it involves precise, repeated angle cuts or guided cuts in combination with the FSK guiding rail and FS guide rail, or exact mitre cuts, the 18 V HKC 55 circular saw demonstrates what modern circular saws are capable of today. And it proves this with every cut, through its versatility, usability, and maximum precision. Day after day. And together with a Bluetooth®-compatible Festool vacuum cleaner in AUTO mode, Festool's Bluetooth® batteries ensure that the vacuum starts automatically when the saw is turned on.
