Perfect for my weekend projects
I had to buy a larger battery to cut MDF board because to smaller ones that came with the drill were cutting out. This is a quieter saw and the circular blades determine it, having switched them.

Light Weight and Powerful
I wanted a light weight, battery operated, circular saw and drill to replace my aging corded circular saw and battery operated drill. I selected Milwaukee's 12 volt family of tools over 18 volt systems because of their light weight and compact size. I have not been disappointed with my choice. The M12 FUEL 5-3/8" Circular Saw with a 6 amp hour battery will run all day for my DYI projects. In fact, I used it to build a deck for my daughter and son-in-law and had no issues with it. It cut through 2 X lumber with ease.

Deceptively great
At first, the saw feels too light and inadequate. However, when using it.....the lightness is fantastic and everything cuts well. I use the saw constantly, mostly plywood or 2"x4"
.......... but all cuts are easy, accurate, and solid. I can't remember the last time I broke out the corded circular. I initially thought a circular sawwould work on an M-18 platform but the M-12 is perfect.

Works great for small projects
I love this little saw for most projects this is perfect. It's not for cutting large lumber, but it will cut 2x4 and plywood with ease.

Good tool if used realistically
Saw bought to carry into backcountry by skis to repairs on cabins. Primary use was to trim doors, 1.5 to 1.75" thick. Cuts often made in 2 passes to reduce stalling saw or burning. I was impressed with battery consumption given the material thickness. Wished rip guide was included, i bought generic guide as Milwaukee brand is way over priced. Be gentle with cut rate and this saw with impress.

Can I use my battery for this? #48-11-2401
Craziedusa on Jun 3, 2016
BEST ANSWER: Yes, all the M12 batteries will work, thought you'll probably want a bigger battery, or more than on of those if you are doing a lot of cutting.

What is the depth of cut for the 5 3/8" circular saw?
JoeCarpentor on Apr 24, 2016
BEST ANSWER: Depth of cut is advertised as 1.5". I've actually found it a TINY bit
deeper than that, which has come in handy occasionally. Like maybe 1/16th
over that. So approximately 1.563"

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
