Where it sits among 165mm circular saws
Scaled against the 19 circular saws with a 165mm blade we list, so other sizes aren't in the mix. Not a score: bigger isn't always better for your job.

Physical & Build
The rail-ready, safety-equipped version of Bosch's 165mm brushless saw. On spec it matches the standard model at 5000rpm and 57mm of depth, but adds Bosch FSN and FSN X rail compatibility, and Bosch confirm its base also rides Festool and Makita rails, plus two electronic features worth having: Stop Control, which halts the blade at the end of a cut, and KickBack Control, which cuts the motor if it senses a kickback. It is a little heavier at 3.4kg and louder at 96 dB(A), the cost of the extra hardware. The pick of Bosch's 165mm saws for anyone who wants guided cuts and the electronic safety net.
