Milwaukee M18FMCS66-0C M18 FUEL 66mm Metal Circular Saw 203mm — Body & Case
Hurry up, only 9 items left in stock.
Sixty-six millimetres of cold cut, no lead. The Milwaukee M18FMCS66-0C is the first 18V cordless metal circular saw with a 66mm cutting depth and 1800W corded performance — running a 203mm blade and cutting faster than the corded unit it replaces.
Dry-cutting technology gives a fast, clean, burr-free finish with no sparks and no abrasive disc, and an electric brake stops the blade in under a second when you release the trigger. The shoe connects directly to the Milwaukee guide rail for straight, accurate cuts with minimal setup, and a large metal chip collector captures debris so you can see the cut line.
Body and case — battery and charger are NOT included.
Compatible with all Milwaukee M18 batteries and chargers.
