• Metal Cutting Blades For Oscillating Saw?

    From DerbyDad03@21:1/5 to All on Wed May 25 07:42:23 2022
    Anybody have a favorite brand of metal cutting blades for oscillating
    saws? A good (decent price) source also?

    I bought some EZARC Carbide blades ("Amazon's Choice") and the teeth
    fell off on the first cut. Got my money back on those. Then I bought some Milwaukee blades at Home Depot. They lasted much longer and cut well,
    but at $12 a piece they didn't last long enough to make me happy. I was
    cutting 1/8" finish nails. Maybe my expectations are too high.

    Anybody know what contractors buy and where they buy them?

    Thanks!

    Well $12 sounds like a good deal. Fein used to charge about $40 for one.


    Keep in mind that this video was made in 2020 so prices will be up
    because of supply chain issues.

    I'll check out the video, but not only have prices gone up, some of the
    higher rated blades that I read about on certain sites have been
    discontinued.

    e.g. There used to be a highly rated, reasonably priced Bosch model
    but that has now been discontinued. As we all know, just because
    that blade was a Bosch doesn't mean all Bosch blades are just as
    good. Good chance it was discontinued because they couldn't
    keep making good blades at that price.

    BTW...I've been pretty satisfied with the Hotbest wood cutting blades
    that you suggested back in...wait for it...2020. That set is now "currently unavailable". Hotbest has a set of 10 bi-metal blade for $12. I guess I
    could try them, but a buck a blade doesn't give me confidence. Sometimes
    you get a real good, real fast, first cut, but then the blades really slow down, especially with metal.

    Precisely! And why I say to not be brand loyal as no one makes the
    best of every thing. I suspect that they were discontinued because
    they did not sell well enough to continue production. Or supply chain
    issues. I have never seen a good selling item be discontinued because
    the cost to manufacture went up, they normally just raise the price.
    However some good items are discontinued because of a replacement version.

    I think most of these blades are probably made in the same factory in
    China somewhere.

    One would think a manufacturer would make a decent blade that lasts longer than 1 or 2 cutting jobs. We had tried using a DeWalt blade to cut through the side of the metal building/camp to install a 4" dryer vent. It took 2 blades and the cut was
    ratty at best.... both blades ruined.

    Though not adaptable to a typical oscillating saw, I Googled to see what Stryker had, that might be helpful. I would suspect their diamond disc blade would do a much better job, however it would not be an oscillating tool. It would only be used
    with a drill, the disc spins, hence not applicable to an otherwise oscillating task. Stryker does have oscillating blades and the hand tools for them, but being a medical device the tool price is out of range for the average handiman, woodworker, etc.
    I did find this diamond disc on Ebay.... the diameter is a bit over 1"..... and at $25, this may be a decent price. Generally, to buy a medical item as this, you need to purchase through a dedicated medical supplier.
    https://www.ebay.com/itm/283828182745?chn=ps

    These medical blades, drill bits and other similar tools we used in surgery are thrown away after one use. They are not autoclaved for subsequent uses. I collected a number of such accessories during my time there.

    You would think a blade manufacturer could easily/readily make a diamond tipped blade, thought the price may be double what we pay now for an oscillating blade. A decent longer lasting blade would be worth the extra cost.

    Long before there were oscillating tools on the market, Stryker had oscillating tools for surgical work. ... Best known by the general public may be the cast saw. Our original cast saw finally started malfunctioning and was replaced. I still have
    and use, now and then, that old saw in my wood shop. It has a circular blade and when one side dulls, you turn it a quarter round and use the next quarter circle of the disc. They cut through wood nicely, but not used for metal cutting.

    Diamond is surprisingly poor at cutting steel or iron--you have to
    keep it very cool. If it gets hot the carbon starts going into
    solution in the iron (carbon is soluble in iron) and you lose your
    cutting edge, and even with oil cooling it can get hot enough to ruin
    the cutter quite easily.

    The carbide or aluminum oxide cutoff wheels on a Dremel work fine and
    are cheap.

    For cutting a hole for a dryer vent an oscillating tool would be my
    last choice. It's really a job for a hole saw or jigsaw.

    However in answer to the original question, the only blades I have
    found for an oscillating multitool that work well on metal are the
    ones sold by Fein.

    Except not all dryer vents are round. Ours is oval shaped as the inlet
    is larger than the gap between the walls. Hesse the pipe in the walls
    is also oval.

    Most of the time, maybe. But when you're halfway out of the window,
    3 stories above a blacktop driveway, with your son sitting on the floor holding your legs, while trying to cut a hole in the facia above you, the oscillating tool is actually the best tool for the job. DAMHIKT

    One that does not use a particular tool does not have much knowledge of
    how it can be a better tool to use.

    Many years ago I was just starting to bust up part of a basement slab to relocate a shower drain. All I had was a sledgehammer and a few cold
    chisels. I mentioned to a neighbor how much work it was. His reply:

    "There's an old saying: If you are working too hard, you're probably using
    the wrong tool."

    The next day he brought an electric jack hammer home from work. ;-)

    I was not knowledgeable of that. Good to know, though. Thanks. I'm not much of a metal person. Most of my metal cutting is with a hack saw and/or tin snips. I had assumed a diamond blade might work fine. They worked fine cutting bone in
    surgery.

    A diamond-encrusted hacksaw blade can work for steel if used wet with
    plain water or an oil-water emulsion. Straight oil won't work.

    One can also get hacksaw blades encrusted with carbide grit; this can
    be used dry.

    And then there is always CBN (Cubic Boron Nitride), which is almost as
    hard as diamond, but can be used to aggressively cut glass-hard steel.
    Like woodworking tools.
