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

The base FUEL 190mm saw, replaced by the FORGE-equipped FCS66GR3 and no longer sold by the main UK retailers. On spec it is a capable 190mm sidewinder, 5800rpm with 66mm of depth at 90° and quiet running at 93.5 dB(A), but it lacks the rail compatibility and FORGE speed of the newer model. We keep its page for old-against-new comparison; if you are buying today, the GR3 is the natural choice.
