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 that is connectivity-ready, taking Bosch's GCY 42 module so the tool can report to the Bosch Toolbox app. On spec it is the same capable big saw as the base model, 70mm of depth at 90° at 5000rpm with BITURBO power, at a trim 4.0kg, without rail compatibility. The connectivity is the reason to choose it over the base version, useful for fleet users tracking and configuring tools. Otherwise its cutting role is identical to the rest of the non-rail 190mm BITURBO saws.
