Whether on a roof or on a solid floor, whether it comes to precise, repeated angle cuts or guided cuts in combination with the FSK crosscut and miter rail and the FS guide rail, or exact miter cuts, the circular saw 18 V HKC 55 shows what modern circular saws can achieve today. And it proves it in every cut, with its versatility, usability, and maximum precision. Day after day. And together with a Bluetooth®-compatible Festool vacuum in AUTO mode, Festool's Bluetooth® batteries ensure that the vacuum starts automatically when the saw is turned on. Mobility and independence thanks to powerful 18 V lithium-ion batteries and connectable crosscut and miter rails. Brushless EC-TEC motor combined with a lithium-ion battery for maximum sawing power. With the FSK crosscut and miter rail, you can cut quickly, mobile, and at precise angles. Safe and comfortable handling thanks to depth adjustment with lowering function, remote control for the pendulum guard, and riving knife. Angle adjustment with quick clamping from 0 to 50°. Secure fixation on workpieces with clamps that can be comfortably attached to the guide rail's grooves. Safe and straight sawing on the guide rail. Convenient dust extraction: the battery communicates via Bluetooth® with the CLEANTEC vacuum's Bluetooth® module (available as an accessory for CT 26/36/48, integrated into CT MINI I and MIDI I), so the vacuum starts automatically when you start the HKC 55. Longitudinal and cross cutting up to 55 mm material thickness. Perfect for mobile use on the construction site. Cuts battens. Saws for outer boards/casts. Cuts boards. Cuts sheet materials. Work comfortably with dust extraction – a Bluetooth® battery automatically starts a Bluetooth®-compatible vacuum in AUTO mode in a box
