                  8 x 4 foot cuts of 5/16" 44w steel plate on one blade and still going. Blades last long with correct technique.

                    Great metal cutting saw
                    I am used to using a grinder or chop saw to cut metal studs for framing.Cutting with this saw will create minimum sparks eliminating the need for a burn permit and designated cutting area.

                    A must for pole barn construction
                    The M18 metal cutting saw makes short work of cutting metal sheeting. I recently built a pole barn and this saw performed flawlessly! Every cut was clean and concise.

                    Awesome saw!!!
                    Great little saw. I bought it before doing a metal roofing job where I had to cut 6 different valleys. What I did was make a little wooden track jig that sits on top of the metal and the saw rides evenly above the ridges and cuts wonderfully. I find myself using the saw alot at the house and shop too since I do quite a bit of work with metal. Great purchase! Wish I had gotten it sooner. My only minor complaint is the saw doesn't balance well with a larger battery attached and tends to fall on its side when you go to lay it down.
