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 standard brushless 165mm saw in Bosch's current range, without rail compatibility. On spec it steps up to a 5000rpm brushless motor with 57mm of depth at 90°, a fast brake, soft start and an LED, and noise is moderate at 93 dB(A). It is the straightforward pick if you want Bosch's current 165mm performance and do not need to run a guide rail. A solid single-battery saw for general second-fix and site work.
