Where it sits among 190mm circular saws

Scaled against the 29 circular saws with a 190mm blade we list, so other sizes aren't in the mix. Not a score: bigger isn't always better for your job.

The verdictOur take

A 190mm BITURBO saw with variable speed, the most refined of Bosch's big cordless saws on paper. On spec it runs a no-load range of 2500 to 5000rpm with an ECO mode that Bosch say adds around 30 percent runtime, gives 68mm of depth at 90°, and keeps vibration under 2.5 m/s². Uniquely in the 18V-68 line its base carries a second groove cut to the Festool/Makita profile, so it runs on Bosch, Mafell, Festool and Makita rails alike. The variable speed and ECO mode make it the one to look at if you mix materials and want to manage battery life across a long day.
