  • Metal saw...anyone know of it?

    A guy from another BBS that I visit showed this... He says it cut through 1/2" thick steel like butter and even collects all it's own chips inside a cover in the saw. Anyone know anything about it? He didn't say who made it or anything.
    I have tools I don't even know I own...

    Believe it or not Harbor Freight sells one.

      Here is a site where you can download video of circular saw cutting 1/4" steel plate.

        Yes, it is true. Our local steel distributor sells them for around $460.00. They have been on the market for a couple of years now. Those who have them swear by them. I gues I'll have to keep using my bandsaw, chop saw, and torch since they are paid for.

          Yup, there was one at work. It got used quite a bit when everyone found out what it did. It was a little noisy as I remember, but a nice tool if you got the money.

            According to the blurb you can use the blade on a normal circular saw. The blades are around US$ 50.

              Are the blades expensive? do they last?

                  who cares if it only lasts a year, or even a week?

                  on a slight side-note, i love the text of that Horror Fright ad:
                  "Cut through metal as thick as 0.118'' (3mm) to 0.275'' (7mm)"

                  well obviously if it cuts through metal as thick as 0.275" then i HOPE it cuts through metal as thick as 0.118".

                    At 4500 RPM, it wouldn't last more than a few seconds (The blade)..

                      I bough some 1" x 6" flat bar from some guys down the road , they sawed off a chunk in about 20 seconds, it left a nice finish like it was milled.

                      I was impressed. It was much better than packing a big long heavy chunk to a bandsaw.

                        The McMaster listed by AHidley is for cutting tin roofing etc. The blade we're talking about here is McMaster# 2431A2 ($56) which has high-temp carbide/titanium tips.

                          The video says you can use a standard circular saw or a "special metal cutting saw". What's the difference? RPM?

                            Yeah, rpm. I had a chance to buy one at the auction I was at a few weeks a go. I didn't 'cause I was saving my money for the lathe if it went at a reasonable price. I should have bought the saw. They were worm gear drive saws in good condition and there were three of them. They went for $25 apiece.

                              "At 4500 RPM, it wouldn't last more than a few seconds (The blade).."

                              Why not? The blade is rated @ 5800 RPM and the saw operates @ 3500 RPM. I'm not saying that it WOULD work on a regular circular saw, just that the saw/blade RPM isn't a limitation.
