The verdictOur take

The base 190mm BITURBO saw, the simplest way onto Bosch's high-output cordless cutting. On spec it gives a full 70mm of depth at 90° at 5000rpm with BITURBO power, a fast brake, overload and restart protection and a 360° dust port, on the AMPShare platform. It does without rail compatibility and connectivity, which is what separates it from the GC and EXPERT versions. For a trade user who wants Bosch's big-saw power and capacity without rail or electronic extras, this is the entry point to the 190mm range.
