The M18 FUEL™ 230 mm (9") Cut-Off Saw w/ ONE-KEY™ is an extremely versatile solution for cutting a large variety of materials. The cordless cut off saw runs on our MILWAUKEE® M18™ REDLITHIUM™ batteries instead of using petrol like most traditional cut off saws. The cut off saw delivers the power to cut reinforced concrete as well as a large variety of other metal and masonry materials. It delivers this performance in a compact and ergonomic design resulting in minimum fatigue for the user. By utilising an M18™ REDLITHIUM™ HIGH OUTPUT HD12.0 Battery (not included), the saw also ensures the user will experience no petrol headaches. The concrete cutting saw produces no fumes so it can be used indoors. It also starts up instantly, eliminates the need to mix petrol and oil, and there is no petrol engine maintenance. The M18 FUEL™ 230 mm (9") Cut-Off Saw is ONE-KEY™ capable, allowing users to track and manage the tool.
