Milwaukee 2786-20 M18 FUEL Lithium-Ion 9 in. Cut-Off Saw with ONE-KEY (Tool Only)

The Milwaukee M18 FUEL 9 in. Cut-Off Saw w/ ONE-KEY is an extremely versatile solution for cutting a large variety of materials. The M18 FUEL 9 in. Cut-Off Saw runs on Milwaukee's M18 REDLITHIUM batteries (sold separately) instead of using gas like most traditional cut-off saws. This saw delivers the Power To Cut Reinforced Concrete as well as a large variety of other metal and masonry materials. It delivers this performance while still being Up To 50% Lighter Than Gas saws that dominate the market today. By utilizing Milwaukee's M18 REDLITHIUM HIGH OUTPUT HD12.0 Battery (sold separately), this saw delivers No Gas Headaches. It produces no fumes so it can be used indoors, it starts up instantly, it eliminates the need to mix gas and oil, and there is no gas engine maintenance. The battery will also work on any of Milwaukee's other 200+ M18 solutions. The M18 FUEL 9 in. Cut-Off Saw also has ONE-KEY integrated so users can wirelessly connect the tool with their smartphone to track and manage the tool.

Like it, but need bigger battery capacity
Batteries dont last long, even with larger options. Smaller ones overheat and shut down in two min. Other issue is that the wheel could be offset more to allow for greater angle options.

Perfect for my patio project
Needed to cut 1” bluestone for a patio project. Used an 8ah and 9ah battery mostly. Even works with 5ah batteries, just let the saw do the work-don’t push it too hard

I bought this saw to cut retaining wall blocks and although the cutting depth is about 1/2” shy of what I need, it’s still been awesome. Using a 12ah battery gives me about 10 cuts through 8x8x4 blocks. Would’ve been nice to get the 14” MX Fuel saw, but at a 1/3 of the price I’m content.

Great saw perfect for any indoor use.
Use the saw to wet cut concrete in doors. By far worth every penny and would buy again if I need another one.

Most using it cutting steel up in the scrap yard. This thing doesn’t say no! Plenty of power to spare and battery life is unbelievable for a tool this size.

Milwaukee is the best
What is not to love! I have only used it to cut stone so far but it holds up to its Milwaukee reputation by slicing through stone like butter!
Love that it is battery powered.

Saw is great, lightweight and very powerful!
As a Master Plumber I use this saw for a lot of cutting such as asphalt, concrete, heavy cast or ductile iron pipe. Very convenient being battery powered, no emissions, no restrictions on where you can use this tool! Highly recommend for anyone interested in purchasing.

Cutting cast iron piping
I used this saw to cut through cast iron piping that I needed to replace and it was the quickest easiest time cutting cast iron I have ever had.
Normally with a diamond blade and a sawzall it takes 20 to 45 minutes but with this I was done in 2 to 3 minutes.
I use a lot of milwaukee tools and will continue to do so as long as they keep making tools that make my job so much easier

Does it actually come with the blades?
A shopper on Apr 8, 2020
BEST ANSWER: Yes it comes with a metal cut off wheel. And come with a nice diamond concrete blade. The saw cuts concrete great. But does use the battery fast. 8.0 n even 12.0. I'm a plumber and cut out sections of sidewalk to run a water and/or sewer. So if I cut a section 18" wide by 4ft long it will use a 12.0. Sometimes tap into a second battery some. So for real big jobs I would go with the MX saw Milwaukee has out. But smaller stuff I love this saw it does what I want it to do. And give it a 10. Hope this helps Thanks
