  • 12" mitersaw used for cut off grinder?



    Has anybody ever used a 12" mitersaw as a cutoff saw?

    Stick a 12" metal cutoff wheel and go to town? The unit I'm talking about has 2HP 15amp motor. Better than my old Makita.

    It would seem the ability to angle cuts to just about any position would be awesome!!!!

    I've seen table saws used this way. Why not the miter saw?

    Sounds like you have the power to run it. Why Not? I've only used mine with a non-ferrous blade for aluminum. The only issue that I can think of is clamping. Most wood working saws don't have the vise to hold the metal in place during the cut and it could wander.

      I have a saw like that and it's a nice one. I would not trash it by dragging metal across it.

        Wood working saws aren't built stiff enough to be cutting any metal except AL extrusions. They also aren't set up with strong enough clamping provisions.

        Basically, like monte said, you're going to be trashing a perfectly good saw, esp if you're trying to cut steel with it.

          Especially when a chop saw is only $150.

          We used a makita miter saw for chopping off small pins and hardened rods and in shot order that saw was junk

            It depends on the tablesaw really.... if you're talking about a Unisaw with HUGE motor on it... (my uncle has one, what an awesome saw with the bessemeyer fence) I can see it doing ok cutting 16ga sheet steel...with some guard adaptations... if you're talking about the $149 craftsman special.... you're just going to let the smoke out of it....

              I think it's not a bad idea-- the Makita mitre saw (14") that my old man has is built way more sturdy than the Makita chop saw that I own. True you would likely have to modify the table to facilitate a clamping system but I think it would work. The mitre saw has a 3 amp stronger motor after all (vs. my old 12amp).

              Granted you would want to be gentle with it (ie. don't let the apprentice get a hold of it). I may try the same thing myself, sure would make some cuts a lot easier.

                Be prepared for all the plastic pieces to melt from the sparks.

                  DON'T EVEN THINK ABOUT IT.

                  Woodworking sliding mitre saws (and I have a Makita just like that one) do not have the clamping vice needed for cutting steel. I have used a cheap woodworking mitre saw for cutting aluminum but wouldn't consider it for steel.

                  For cutting steel, particularly at any angle other than 90 deg, tremendous pressure us put on the material being cut, trying to draw it into the blade. (Maybe best to be thought of as pulling the material through the vice). A woodworking mitre saw lacks sufficient holding capacity.

                  On my Porter Cable Cold Cut saw, I even add additional C-clamps to hold the stock (in addition to the built in vice) in place. Without the c-clamps I've had it pull the stock into the blade enough to bind the blade.

                  To those who say that it won't happen because of the rotation of the blade, believe me it does.

                  Metalworking chop saws are too inexpensive to ruin a good sliding mitre saw.

                    Just let us know how it goes.
                    I am doing the same thing only I am using the HF 12" compound slide miter chop saw on aluminum. $159
                    For steel get a 4x6 bandsaw if you don't like a chop saw.
                    BTW, Evolution makes a similar saw only made to take the abuse that may fit the bill a bit better for ya

                      Here is the Saw FushionKing was talking about. Looks pretty good and it only 210.00. Not sure about shipping.

                      Seems to have a standard miter type fence. As for clamping of the work piece It seems like it would be easy enough to add something on.

                      Specs

                      - Featuring RAGE technology: Cuts Steel, Aluminum, Wood & Plastics easily without compromise.

                      - Fast and clean cuts, the FURY3 leaves virtually no burr and offers an instantly workable finish.

                      - Economical performance, the FURY blade system will out perform traditional TCT blades*.

                      - The Hi-torque gearbox reduces motor stresses, improving performance and durability.

                      - No coolant required and virtually no sparks are produced.

                      - High quality construction.

                        Why not get the real thing? They are pricey, but you only cry once with these...

                          I can certainly appreciate the accuracy and quality but, I would never stop crying if I bought that thing....tons of money and too limited on angles for my line of work
                          I think there is still plenty of room for innovation in the chop saw realm myself.
                          After I fry my HF saw I plan to either get a Rigid or Dewalt...and the Milwaukee is looking pretty nice as well. But like I said I am only doing aluminum.

                            I would be crying too... that's why I don't have one either. Just throwing options out there. I'm happy with my 7x12 horizontal band saw for most stuff.
